First, A lot of these Reviews are out of date...3 years old.That is because the Zeo went out of business in 2013. Check them on Wikepedia for latest.They forbid anyone to make replacement sensor headbands and shut down their server.It is still the Best Alarm clock out their by far.The important information for you in late 1016 is that a reputable company ResMed bought their patents.They are selling a product "SPlus" that is listed currently sold on Amazon for $ 50.It measures and provides much of the same information that Zeo used to provide.Several differences. a) the computing power is offloaded to your smart phone, hence the low cost. b) their is no head band or wrist band. It uses a non attached sensor that uses special frequency waves to sense your breathing and other movements. Much more comfortable.S+ By ResMed Personal Sleep Solution

I was very excited to receive my Zeo since I've heard very promising things. I bought the clock not to address sleeping problems, but to find out more about my sleep cycles and to be waken at the best time (via smartwake) during the transition into or out of an REM cycle. The clock itself is well designed and very user friendly. The headband and sensor fit snug and you barely notice when sleeping. The unit was well packaged (besides the safety seal being broken).The clock did what it was intended to do the first night and woke me up during the beginning of an REM cycle which definitely had a positive impact on my day. The second night the clock was working perfectly before I went to sleep, but when I woke up clock was powered off. I checked the outlet to see if there was a power outage, but it wasn't the outlet! My Zeo display was entirely blank everytime i plugged in the unit! I'm not sure what went wrong, I called customer service and they said it might be a power supply issue so I'm waiting for them to analyze an sleep.dat file I sent to them. But its the weekend and customer support is only available M-F, so i'll have to wait to give you guys an update! The clock has promise...when it WORKS!!!

Also - The safety seal on the inside of the box was broken (which apparently is a recurring problem with other people who purchased Zeo's), the Zeo headband only took a few minutes to reach a FULL charge (the manual said it takes 2 hours to fully charge the headband), and the extra sensor was not included (which apparently is a miscommunication on Zeo's part, because the $249 model isn't supposed to include extra sensors for the headband). I'm worried that I might have a refurbished unit...but there is no way I can tell, I just have to wait until Monday to talk to customer support so I can send the unit back. I'm very skeptical at this point...spending $249 for this unit only to have it break on the second day of usage.

I have spent a lot of money in the past both on my own EEG equipment and on professional PSG testing at hospitals, all in an attempt to understand my sleep architecture. This machine is so much cheaper than those alternatives and provides an incredible amount of data. Zeo is a product WAY ahead of its time.

******* GOOD THINGS:
Can't say enough.
How good is the data? Their ZQ measure absolutely correlates with my subjective mood. My scatter plots show a nice linear correlation.

I have learned a LOT about my sleep (I tend to get a ridiculous amount of REM sleep but very little Deep sleep), I can also track changes in sleep that occur when I exercise or take a medication.

It's very comfortable and easy to use. Put it on at night, take it off in the morning.

Tech support has been quick and polite and when I had a part go bad they immediately sent a replacement.

******* BAD THINGS:
1) If you use it for short naps you have to quickly write down the information from the base-unit before the data disappears. It would be nice if naps were handled better.

2) (NOTE: THIS ISSUE HAS NOW BEEN SOLVED, SEE COMMENT FROM ZEO BELOW REVIEW) There is no way YET to get ALL of the data onto your pc without uploading to the company website to decrypt. If they go out of business customers will be out of luck. Zeo has written on their blog that they are going to open-source everything so that a geek such as myself will be able to access the data right off the card. So this problem is hopefully going to go away soon.

3) I kept getting communications dropouts and I had to rule out quite a few problems, then call tech support. They replaced my headset immediately and the new one was indeed more stable with no dropouts in data. What bothers me is that as a new user I had no way of knowing that the connection was less stable than it should be.

So ******* NOTE TO NEW USERS:
The JEB icon should display pretty quickly when you put on the headband, in say 15 seconds. It should persist even if you move around a little. Test the headband out during the day and be sure it's behaving correctly.

Note that none of the bad things above are a big deal. Even one month of data of this quality would be worth it to me for $200. I think the people with very high expectations have never had to pay for real (and often useless) PSG's and EEG's and so they don't realize how easy and cheap the zeo is by comparison.

***** MY WAY OF USING THE ZEO:
I log into their website, upload the data file, download the spreadsheet data to my pc and plug the numbers into my own graphs and charts. That's pretty much it.

****** AND SO
So there you have it. There are a few pitfalls, but for people who are desperate to get valuable data on their real, 'at home', sleep architecture, Zeo is an incredibly valuable, one of a kind product.

***** Update: 2013.6.1
I am SO sad to see this company shut down.
If another company takes over the product, here's my wish list:

1. The user should be able to ask the machine to run a self-diagnostic. (right now it's very difficult for a user to know if machine is running as it should, and this does not make user feel confident.).
2. User's should be able to analyze and chart their data independently of a website, a website which will only disappear if the company goes out of business. (zeo allowed downloading of all data in spreadsheet form, but that was it.)

1.0 out of 5 stars Needs further development and might then be usable

Zeo Personal Sleep Coach

FIrst, I hope that Amazon are willing to publish this negative but completely honest review.

I don't submit many reviews as I buy so much from Amazon, but the Zeo was such a bitter disappointment that I thought I had to publish this review to help other people make an informed decision on whether to buy.

I'm an experienced embedded hardware/firmware engineer with a pretty good idea of what the Zeo is doing, in detail, so I think I can comment from a position of experience.

There a three key problems with the Zeo that prevent it being a BRILLIANT device that would probably work as advertised for more people:

1) The headband has to be so tight to pick up a good signal that it a) gives me a headache, and b) does indeed leave deep depressions in the forehead after a nightimes wear. I did experiment briefly with ECG electrodes wired via 'poppers' to just the 'module' on an insulated headband, and this did solve these problem, but at a cost of 3 ECG electrodes a night. I'd suggest that Zeo supply and recommend the use of a conductive gel applied as just a small spot on each of the 3 standard electrodes as, whilst I didn't try it, I think this would enable the headband to be loosened and relieve the headache and forehead marks problem. The supplied module/headband is also problematic if you have a large head (I'm 7 1/8 UK sizing) and may explain why I had to tighten it quite so much to get good contact on all three electrodes.

2) For both my girlfriend and I, the Zeo simply did not show the correct sleep phases, so had no chance whatsoever of performing its 'smartwake' function of waking you during the 'best period - Light/REM sleep' in a user defined window before the alarm time. For me, unless I was actually walking around, the Zeo said I was in REM sleep if I purposely lay quietly in bed watching the display, within a minute of me laying down, despite beeng fully awake throughout (I tried this check several times for up to 20 minutes and always got the same result) . For my girlfriend, it said she was awake most of the night, when she actually slept extremely well and awoke refreshed in the morning.

3) On to the crux of the problem, and also my suggested solution: Zeo customer support are totally defensive of their product, and, despite MANY emails, said that the data files I sent them from my girlfriend and I were normal, when they blatantly weren't. I believe I know what is needed to fix the bug with the Zeo, and that is a calibration routine (I'll explain in a moment), which I suggested to Zeo and was told they had no plans to implement such a thing, and, possibly typical of their attitude, that "maybe Zeo is not for you", so I have had to return it, which I have now done, as it is basically defective.

Going on to my proposed solution: The Zeo seperates the minute EEG voltages into Alpha, Beta-1 2 and 3, Delta and Gamma waves by means of Fast Fourier Transform (FFT) algorithms before passing them to their "marketing speak' named "neural network" for processing. This can only possibly work if the decoded signals are in a range and of an amplitude that the Zeo's "neural network" regards as "normal". Anything else is certain to give incorrect results. My suggested solution was and is a simple calibration routine whereby the individual user lies quietly, but awake, in bed, and the Zeo measures the average and deviation of each of the different rhythms, and then "normalises" them in amplitude and deviation to what the "neural network" expects. I don't believe this would take any more than 1-2 man days in total (I think I could do it in that time if I already had their knowledge of the firmware and the programmable signal processing chip used). This would probably suffice for 90% of cases, but ideally the algorithm would also be made adaptive and adjust its multiplying and scaling factors based on ongoing data for an even better result.

Now, I know Zeo appears to work for some people, but, for many others, I suggest it doesn't, and either gets returned, or more likely ends up being kept as an expensive alarm clock (which doesn't even have stero sound or adequate volume, and also doesn't allow the download of your own MP3 music files from the SD card for the 'wake-up' music - you can update the firmware from the SD card so the capability exists). As a result, Zeo are losing their key 'word of mouth' advertising that will sell an expensive product like this, and must be losing out on at least 50% of possible sales in my opinion as people will pass on the bad results rather than being able to recommend the device to their friends.

Sorry for the long review, but I wanted it to be as accurate and informative as possible.

Until at least a calibration routine is added (I've asked then to inform me if they do so, when I may re-purchase from Amazon to see if it does then work), I simply cannot recommend this device to anyone.

5.0 out of 5 stars Extremely effective, educational, and analytic tool to improve sleep
Reviewed in the United Kingdom on December 17, 2011
I have been using Zeo as a sleep monitor every night for 8 months now. It is worth every penny, as it has been invaluable in identifying my sleep problems which led to the diagnosis of a serious medical condition. My consultant found the reports of data gathered by Zeo were instrumental in helping them understand my sleep problems along with other symptoms and reach a diagnosis.

There are two main areas to review - the hardware and the software.

The hardware consists of a wireless headband and a bedside monitor. I found the headband surprisingly comfortable to wear. The band is very soft material with adjustable velvet for added comfort in the area of headband that sits behind your ears. I have experimented with tightness of the band and found it doesn't need to be tight in order to function accurately. If it is too loose, it will likely come off in the night, and if it is too tight, it will leave little indents in your forehead from the silver sensor pads, but these have faded by the time I have a shower. It is so comfortable that I don't notice it is there.

The bedside monitor has a large display which provides live feedback of the various sleep phases you have throughout the night and the data is recorded to an SD card. I have had difficulty getting to sleep and difficulty staying asleep, so through the night I can see what sleep I have been getting and how much wake period I have had. I have not found any inaccuracies with reporting of time to sleep or wake times, i.e. it has always reported me as being awake when I am awake, and when I wake in the night from a bad dream, and it shows that I was in REM prior to wakening. Interestingly, on the mornings that I wake up and feel completely sledge-hammered with exhaustion, I have been awoken from a long REM phase. When I wake from light sleep, I never feel so rough. Zeo has a tool for that problem though, with the "SmartWake" function; it lets me set a window in which it is ok to wake up (e.g. between 6 and 6.30am) and it will avoid waking me during deep or REM sleep and will find a window when waking is easier, such as transitioning between sleep phases. The bedside monitor also has all the functions of a normal alarm clock and a battery backup incase of power failure. I can review my sleep data on the bedside monitor, or use the SD card to upload the data to MyZeo online.

The `software' is the data from the SD card uploaded to a suite of analytical tools via an account with MyZeo. This has two parts to it - a coaching program and a bundle of analytical tools. The coaching program is absolutely brilliant! It is a 7 stage program, which I have taken my time to use and learn from it, and it has really helped educate me on sleep-stealers and the steps to take that will improve sleep quality and time asleep. I like the fact it has educated me as well as helped me change behaviours that affected my sleep. Despite having a sleep disorder, the coaching program definitely helped improve my sleep.

The analytical tools are very informative; for example, showing you things you think help your sleep actually make it worse - such as drinking alcohol, exercising too close to bedtime, eating too close to bedtime, having a bedroom full of gadgets etc. The tools can help identify patterns, trends as well as cause & effect. You can also print out a variety of reports to take to a health professional if required. The website also has a Knowledge Centre giving you access to loads of articles, research and knowledge documents, I found these really helpful in helping me change behaviours necessary to improve my sleep.

The Zeo has completely changed my attitude towards sleep through education, coaching, and knowledge of my sleep phases, quality, and duration. It is so helpful I am continuing to use it on a nightly basis as part of my ongoing health monitoring.

If you have sleep challenges and want help to improve your sleep, I really recommend the Zeo. It's not a quick fix though, I found to get most value from the data, tools and coaching, it is worth using it long-term and making it part of your nightly bed-time routine.

1.0 out of 5 stars Yes, it leaves red blotches on your forehead.
Reviewed in the United Kingdom on April 26, 2011
I saw the other single negative review "burnt my head" but tried the product anyway. Unfortunately, he was right. "Burnt" is a bit strong, but it certainly left red blotches on my forehead. These dissipated after about 24 hours but I can't go to work with red marks on my forehead! I don't think it's the electricity or anything, just the way the pads on the headband contact with the skin, I guess. I did persist with as loose a setting possible; the unit gathered data fine but still left marks.

I have returned for a refund. It's a shame as otherwise it looks like a great idea. I hope the manufacturer improves the design of the headband and I'll try it again when they do.
