Well, since I've relied on the reviews of others at Amazon, I suppose it's appropriate that I take the time to share my experience with the rest of you.

I have for decades had a devil of a time with both regular insomnia and with periods in which I didn't sleep at all for days. So the notion of a little star-trek like device to sample my brain waves and allow me the feedback to possibly sleep better seemed like a neat deal.

And indeed, it was Amazon's "deal of the day" marked down to $199 on the bleary morning I ordered it last month, after several successive nights of less than 2 hours' sleep. Their featuring of the item seemed like kismet, and $200 for the possibility of improving my sleep seemed like a pittance.

I've now used it for several weeks, and will be returning it. I'll try to list the pro's and cons here:

Pro's: It's not uncomfortable to wear. I consider it brilliantly designed, the interface intuitive, the memory card easy to remove and replace even without looking at the slot, the way the recharging cradle seems to have a magnetic lock which enables quick and accurate replacement. The support staff are courteous and prompt in answering questions. The web interface is a nice bonus and graphic display, although I'd have preferred a simple home program. But they do let you download the info after you've uploaded it, where a subset of it could be put into an excel spreadsheet if anyone wanted to.

Cons: It doesn't work and is bloody useless.

I suppose your mileage may vary, and perhaps I have an unusual brain, although past MRI studies haven't shown any mutant extra lobes or anything, which was vaguely disappointing though expected.

But the device just seems to make stuff up. It gives the impression of a Chinese knock-off of a working device, like those MP4 ipods you can get on ebay which work for a day and will only store three songs before the actual ram is full.

Specifically, IF I am asleep, it will dutifully create a graph showing periods of REM, deep sleep, light sleep, etc. And I could look at that and go "wow, look at this great telemetry". Except that it does exactly the same thing while I'm awake. Indeed, even when I put it on with my eyes open, it immediately reports I'm in REM sleep. Last night due to an injury, I lay there wide awake for nearly two hours. Annoyingly, I was able to pick up the recording device and see, in real time, that I was in REM sleep, or in light sleep, and hadn't woken up at all. I could actually stare at it as it logged my sleep status every 5 minutes, and see it tell me I was asleep. Bottom line, it considers me to have been solidly asleep for over 7 hours last night, when I was only unconscious for three.

Nor was this the first time this was apparent. The first couple nights I couldn't help noticing that it STARTED me in REM sleep as soon as I put it on. As long as I wasn't talking out loud, it didn't consider me awake. Contacting the polite and upbeat Zeo support staff via email, I noted this, and was advised that it was not good sleep hygeine to stay awake and think about things. Wow, why didn't I think of that? No, I explained, I agree that insomnia is antithetical to sleep rather by definition, the point is that your invention doesn't work. They assured me that they would contact their tech person and get back to me.

Within a day I got back their tech advice: the Zeo was designed to work on normal healthy brains. If it didn't work on me, the implication went, then my brain wasn't normal or healthy enough to meet the standards of its product. So it wasn't their PRODUCT that didn't work, it was my brain.

What provided a colorful backdrop for this was that although I'm a 59-year-old insomniac, the machine was giving me the "Z score" of a 20-year-old olympic athlete. A night lying there getting terrible sleep and being awake nearly constantly would show zero wakings - not even being awake when I put the thing on - And so would say that I got 8 hours sleep including 4 hours of REM, and give me a sleep score of over 90, not only counting me as being asleep the whole time, but giving me bonus points for all that REM sleep.

I know, too, that it will say I'm in "light" sleep while I'm conscious, because last night, having nothing better to do, I held it and stared at it, daring it to continue to tell me I was in light sleep. But after five minutes of staring, it did. The ONLY incorrect thing it has NOT done is report that I'm in deep sleep while I'm awake.

"Many times we don't remember sleeping when we really do", notes the Zeo techs. OK, true enough, but again, your product doesn't work. It considers me in REM sleep or light sleep from the moment I put it on. I suppose I could consider the philosophical proposition that I have never yet in my lifetime been actually awake, which might explain a lot; but I'm not sure why I'd dream about buying a product off Amazon that doesn't work.

Frankly, since the thing is wildly inaccurate while I'm demonstrably awake, I'm less inclined to trust what it says I'm doing when I'm actually asleep. Ironically, I get worse ZQ scores when I sleep better, because I'm actually sleeping and don't lie there in the dark trying to sleep for 9 hours. I've taken to giving the ZEO display a display of my own upthrust middle finger each morning as it gives me a 95 for a terrible night of sleep and only a 64 for the best night I've had this month.

So to sum up: it is apparently useless for people with brains like mine. Inasmuch as there is nothing else notable about my brain, it may be useless for a lot of people. In other words, how do you know it isn't just making stuff up? The novelty of seeing a graph of your sleep stages is cool, but there is no way to tell whether it corresponds to objective reality. Ultimately it may be a good placebo for those who have more faith in machines than in their own fallible protoplasm, but again, and to me quite salient: it doesn't work.

I will note here that if the good folks at Zeo wish to tweak the product so it DOES work, I'd happily buy one even at the normal price. I hereby offer to be a test subject for them if they build a "mark II" version that will actually do what the current one purports to do.

So my next adventure will be sending it back, and I'll report back if that becomes any sort of adventure. Of possible concern is the fine print: they offer a 30-day money-back trial, BUT the machine must be returned in "salable" condition the same way you received it. Say what? You can't even unpack the thing without tearing open several plastic bags, and you can't plug it in without unwrapping the cord, etc. I guarantee that although I will return it in its pristine unworking condition as good as it ever was, that they'll have a hard time reselling it without repackaging.

Also, I note that unlike my other Amazon purchases, I can't just go to my account and do a return, I have to go through the company itself.

So to sum up, I think two stars is a pretty charitable score for a product that doesn't work. It's a masterpiece except for that little fact.

UPDATE 3/5/10: I asked for an RMA and they sent me one, but noted that I had to cover the return postage. So I decided to invoke Amazon's A-to-Z return policy and submitted a claim to make sure I got the full refund. Very quickly thereafter I got a nice note from Zeo saying they'd send me a prepaid UPS label to return it - which they quickly did - and assuring me that they would give the full refund. So I thank them, and I also thank Amazon for their policy - it never hurts to buy through Amazon when you have a choice.

Overall, I am satisified enough with my Zeo to keep it past the 30 day return period. However, if there was an alternative to the Zeo I would return this and try the other product.

I too have sleep Apnea, and actually stopped using my CPAP machine for a year after I first got it. My feeling was that the machine was waking me up more than Apnea was due to it shutting off and mask leaks. A second sleep study revealed an outright dangerous situation, and they had to stop the test after an hour and put me onto a CPAP machine. I still have a choice of masks, so I wanted to see if a different style mask would still cause the problem. The Zeo pretty much has ruled out the CPAP as being a problem, I think. More below.

I also have been trying to stop taking an anti-anxiety medication. The last time that I tried I developed Syncope, a condition where you randomly pass out and fall down. It's unclear whether the cause was the medicine, the Apnea, a combination of the two, or something else, but the doctors blamed it on the apnea. The Zeo, however, has shown me that although I fall asleep faster with the med, I don't go into REM or deep sleep hardly at all. It also showed that as I tapered down the med, it took me longer and longer to fall asleep, 1 then 2 then 4 hours, but it was a 'good' sleep. I could determine after a week or so that my sleep patterns went back to 'normal'. The first time I tried to stop I started nodding off uncontrollably at my desk, and at least then I knew enough about what was happening at night to cause it.

I couldn't have tracked and found out these things without the Zeo, and if it weren't for some other issues I would recommend it without hesitation.

There are some accuracy issues. I know that I have been regularly waking up and the Zeo does not record it. This is really important to me to monitor the above conditions, and in trying to isolate myself with a sound machine or 'sleep music' cd's and seeing if something else is waking me up. For instance, I have a feeling that when I turn on my side the CPAP mask is hitting the pillow and nudging away from my face, waking me up, but I can't tell for sure.

What really bothers me more than anything is the fact that you can not get an accurate representation of your sleep without uploading your sleep data to Zeo. There is no software to run on your PC to see your sleep info, all of the displays run in your web browser from the Zeo website, and all data is kept there as well. If something happens to Zeo, you are left with nothing but a really expensive alarm clock. The display on the unit does not show the time to fall asleep nor accurately portray deep sleep, and cannot be saved or printed.

Some people have posted their concerns about privacy of information as well. I personally don't have a problem with it, but Zeo sells or will sell or is trying to sell or is thinking about selling (they're not sure) to third parties. One person pointed out that his sleep data could be subpoenaed in the event of a traffic accident or something, and they could say you were not getting enough sleep and caused the accident. They added an 'opt out' option to their web page, it's not very prominent but it's there. The individual stated that he would just use an alias when setting up the web account, probably a good idea. Privacy issues aside, your sleep data is encrypted and you can not read it off of the SD card. You can, however, upload your data to the web site and download a .csv file back so you can import it into a spreadsheet. It does not, however, resemble anything other than a string of numbers, you could not read it or graph it. None of these issues are readily available for reading on their web site, you need to dig around a bit and find a blog that is addressing them.

Which leads me to my last little gripe. When I posted in their blog that it was a problem not being able to see the data locally, and I could not use the device if they went out of business, their response was that they were on the 'Today' show. Ok, but when I opened up the Zeo box and checked the contents, I was short a sensor pad. When I emailed them about it I was told that they stopped including it to save money since they lowered the price. Doesn't sound like a financially strong company to me if they have to exclude a little cheap pad.

So, if it wasn't so useful, even with the problems mentioned, I would return it. If I had known about the data being on the website only I would have never bought it. But, there really is no alternative that I know of (especially on the 'Today' show).

I have trouble sleeping and thought I would try the Zeo. The MyZeoe website comforted me with language of "30-day risk free trial". I purchased the unit and began using it.

However, after using it for two weeks I realize there is a limitation in the device. Basically, it sometimes takes me a long time to get to sleep at night. The Zeo, however, tends to think there is no way it could take a person 3-hours to go to sleep and truncates my time to sleep to 12 minutes.

No big deal, the Zeo is not for me. I started the return process and this is part of the exact email I received back from Zeo:

"Returned merchandise must include all original accessories, literature, documentation and packaging in the same saleable condition in which you received them. Refunds for returns will only cover the purchase price and any sales taxes charged. Refunds will be processed within 30 days of receipt of your returned product, in the same form of payment as your original purchase. Refunds will not be made for any shipping and handling charges.

Damaged merchandise, cosmetically or otherwise, may be subject to a restocking fee equal to 30% of the price paid (not including taxes). You are responsible for and must prepay all return shipping charges and shall assume all risk of all loss or damage to the product while in transit to Zeo."

Feels much different than a "30-day no risk trial" that they spoke about on their site. Thought I would warn folks about this...

That being said, I like the concept of the product and wished it had worked for me.

I've been challenged by sleep issues for over 38 years. I've been to a sleep clink, multiple "sleep" doctors, tried meds from my general practitioner, etc. and nothing seemed to work. I was resigned to feeling extremely tired everyday from the time I woke up until I went to sleep. My friends nicknamed me the "vampire" because I was literally awake so much of the time. I was able to confirm that I didn't have apnea via a sleep clinic and found that most sleeping pills (Ambien) were useless for me as I just woke up anyway after a few hours.

I've been using the Zeo regularly for five months now and it's made a massive difference in my quality of life. I learned within a couple of nights of use that my sleeping pattern consists of two to three ninety minute sleep cycles (3 to 4.5 hours), followed by waking up for two hours and sleeping lightly for another hour or two. I was literally getting 4.5 to 5.5 hours of sleep in any given 7 to 8 hour period and thus was constantly tired. I've was able to use the data from the Zeo (I literally took a print out of the graph from uploaded data from the [...] website to my doctor) to determine that I needed to consider medication that would help me stay asleep (The Zeo confirmed that I can literally go to sleep in 2 to 5 minutes, so that's not my issue.) Zeo gives you an idea of how well you are sleeping (relatively) with a daily "ZQ" score. (I started at 50/100 and now am up around 70/100 on average. I even got 100/100 one day!)

I feel much better and more awake each and every day thanks to this product. I have used it to control for caffeine, alcohol, travel, kids waking me up, etc. to get a much better understanding of how all of these things effect my sleep.

The Zeo can help you really figure out in great detail what is going on for you personally with your sleep. You might need to stop drinking caffeine earlier in the day (I stop at 2:30 PM now), encourage your young kids to not wake you up at night (I literally now give my kids dessert after breakfast, but only if they don't wake us up in the middle of the night (and yes, this does work)). Zeo can help you figure out exactly what's going on with your sleep to a much greater and more detailed extent than any medical professional outside of a sleep lab. It's proven to be a great value for me and I highly recommend it to anyone who is challenged with sleep and daily fatigue.

I've read through the reviews---lots talk about what sleep is and how important it is, etc. Think we all get it. So, my review will address the important question---how did it work for 30 days. Short answer: I'm returning it today.

I wanted this to work. So, it had that going for it from the start. The headstrap is not uncomfortable and after 2 weeks, didn't even notice it anymore. While wearing it and sleeping, I never had issues with it falling off or dropping signal. Each morning, the graph showed consistent patterns of the four sleep stages. A little too consistent.

I want to test it to see if I could trick it. I laid still for about 15 minutes. Closed my eyes. I tried to "act" like I was asleep by resting myself and letting my mind wander. Not once did the zeo indicate anything other than "wake". Passed the test.

Now, let's talk about actually sleeping. I don't have any sleep disorders or unusually stressful activity occurring. A few of the night I woke up and noticed the zeo would eventually indicate "wake". However, over the past week I've been more scientific. If I woke up, I wrote down the time and went back to sleep. I've found the zeo simply never registers these events. In fact, last night I woke up around 4:30AM and stayed awake (resting) until the alarm sounded at 5:30AM. Zeo showed I was in REM. Wrong. Another time I woke up, wrote down the time, and fell back to sleep. Zeo said "Light" sleep and never "awake". Wrong.

So, now I question the accuracy overall. If it was wrong these occasions, just how reliable could it possibly be? Does it just erroneously measure sleeping? Certainly is this case the times I noted. Does it falsify data? Don't know, but the graphs sure do look "normal" all the time.

I really wanted the "Smart" alarm to work, but it was just too unreliable. Also, it does not make sense that it will wake you early only when starting to dream or coming out of dream stage. I stayed in "light" sleep the entire 30 minute window---a condition that will not trigger the alarm. WHY?? I'd rather wake up during a "light" sleep than when just about to dream/REM.

Overall, hard to scientifically measure the reliability and accuracy of this device. All I can suggest is do your own testing. Whenever you wake up, write it down and compare it to zeo when you awaken. Several times I woke up but when I didn't write it down. Zeo would say "REM" or some stage other than "wake". I thought...maybe I was just dreaming that I woke up. Now, I seriously doubt it.

Good luck.

I am 57 year old man with severe, complex sleep apnea. I sleep with a Cpap machine. I have found the ZEO to be an excellent tool to help me monitor and understand my sleep. A small head strap monitoring device reads my sleep patterns through the night. The ZEO base station documents the information. When I wake up I place the headband device in a cradle in the ZEO base and in a few seconds the data is transferred. I then remove the data thumb drive from the base station and plug it into my computer to upload the data and review my sleep profile from the night before. I can see how long it took me to get to sleep and a breakdown of time spent in light sleep, deep sleep, REM sleep and any awakenings throughout the night. I can also view my prior sleep profiles. After accumulating a week or two of sleep profiles I get personal feedback and coaching from a ZEO staff member.

The whole system is really well done and ZEO is a tool that I have come to respect. I am a successful business owner and I am usually skeptical about many of the new gadgets that come on the market, but ZEO has made the cut as a very important and useful tool.

ZEO has a 30 day return policy, no questions asked. I assume many of you have done overnight sleep tests at a sleep clinic. The information gathered there is more in depth but you only get this data occasionally. The ZEO fills in the gaps between sleep tests and is giving me regular and consistent feedback.

One more thing. My sleep doctor here in New Mexico happens to be a very sharp and committed man who has written one of the best books on sleep apnea of all the books that I have read. His book, Sound Sleep, Sound Mind: 7 Keys To Sleeping Through The Night is a must read if you are having sleep problems and want to know what can be done about it. I know first-hand how debilitating sleep problems can be. Take charge of your sleep life and start to live again!

I don't have any serious sleep problems, but tend to wake up groggy like a lot of people and thought this device could be useful. I thought it would be interesting to find out about my sleep patterns without going to a lab. The headband is ergonomic and not noticeable while you are asleep. The smart wake feature - which wakes you up during light sleep in a 30 minute window that you set - helps me feel significantly better when I wake up. But the most useful part is seeing my sleeping pattern on a graph. I can see how certain things like alcohol or caffeine affect my sleep. It is well worth the price given how much time we spend sleeping.

I have used the Zeo system for over two months now. The system works in two parts. You purchase the base hardware for $250. You can also purchase one year of "coaching" for an additional $100, $350 total.

I thought that this might be helpful. I am a fit, 25-year-old man. I have never had trouble getting enough sleep, but I found that I was often still tired in the morning. I was very excited to try the product. Specifically, I was excited about the feature that gently woke you up in the morning at the optimal time.

I have been very impressed with the hardware.

The headband is comfortable. After a couple nights, you cannot even notice it. The headband does not disturb you when you sleep. It will occasionally fall off if you roll around, but that has only happened to me once or twice. You want to make sure that there is nothing obstructing the path between the headband and the base station, or you won't get complete data. I have the base station sitting on the dresser about 10 feet away and it works fine.

The alarm is excellent for waking you up at the optimal time. There are several other products on the market today (watches mostly) that claim to wake you up at the most optimal point - when you are in the lightest stage of sleep. These watches rely upon your body movement. People tend to move when they are in their lightest stage of sleep. However, not everyone does this. I am one of those people who stays stationary most of the night. When I tried one of these products for a week, it failed to wake me up during the "window" once. My wrist was also under my pillow another night, so I didn't even hear my alarm.

The headband actually senses your brainwaves and wakes you at the optimal time. I have been shocked at how well the device works from this perspective. I have my alarm set to wake me up no later than 7am. I am willing to wake up anytime 30 minutes prior to that (6:30am). The alarm has woken me at 6:32, 6:47, 7:00, 6:38, etc. Several times I have naturally woken at 6:40 or so, only to have the alarm go off about 5-10 seconds later - the system recognized that I was awake.

Waking up at the optimal time has made a major difference in how I feel in the morning. When I wake up, I am coherent and I am capable of logical thought. I do not feel overtired or as if I just fell asleep. The product has been excellent in that regard.

However, you still need to follow basic sleep rules. Wearing the headband does not mean you can sleep for only three hours and feel great in the morning. You still need to sleep 7-8 hours per night to get the desired effect. However, if you do sleep this much, you will definitely feel it in the morning.

My coaching and customer service experience has been terrible. As I mentioned, I paid $100 for one year of "coaching." This would be great, except I can't even get my data to be coached! I have been able to upload my data to the website without a problem. However, despite uploading over 30 nights of sleep, I still haven't "selected" the requisite seven nights of sleep data to fulfill my initial coaching requirement. I sent emails to customer service and even chatted with their reps. They all gave me the same response. They all told me to wait for the "second screen" to appear after uploading my data. It would allow me to select which data I wanted to use for coaching. THE SECOND SCREEN NEVER APPEARS!!! I have told this to multiple people but they keep sending me the same step-by-step instructions. I am very, very good with computers. I've never had such an awful customer service / online product experience.

In short, it's definitely worth $250 to have an alarm clock that actually wakes you up at the best time in the morning. It's not worth it to pay for the coaching.

i was really hoping that zeo would be a great tool. in most respects this product is a good buy.

where it fails is accuracy, and for what this product is aiming to do, accuracy is everything. i've had it for a week now and last night, my worst night of sleep, i somehow scored the highest ZQ yet. it doesn't properly catch waking transitions, which is the biggest factor in skewing results. and if it can't do that right i can't trust that the REM, light, and deep sleep readings are accurate either.

(for reference, i've had two medical sleep studies done and have been diagnosed with minor sleep apnea. i wake up several times an hour, and zeo is only sensitive to big wake ups, like getting out of bed to go to the bathroom. but there were a couple of instances where it didn't even capture that.)

if they can get the sensors to be more sensitive and accurate, i'm willing to try this again. but for now it's going back.

I've had my Zeo for over six months and last night I had experienced another example of it's frustrating inaccuracy. I recall several vivid dreams between 4:30am and 7:00am and yet my Zeo shows me as awake for almost that entire period. Of course my sleep score was very low as a result. Mistaking vivid dreams for being awake is an ongoing problem. I talked to Zeo support online about this issue and the support person admitted that Zeo's will indeed confuse vivid dreams with awake states. I wonder how may other times during the night did my Zeo mistook dreams for being awake? This situation makes it very hard for me to trust the results I'm getting from my Zeo.

Too bad, because the device is very well designed and the head strap is comfortable to wear. If only it were reliably accurate.
