I have been using this device for 1 full cycle and overall I like the product. The alarm feature is very nice and convenient to ensure that you are testing at the same time every morning (which is important when charting). It would be nice if there was a backlight on the screen but this is not a huge issue since all the temps are stored. The biggest negative about the device is how long it takes to record the temperature - somewhere between 3 and 5 minutes usually. It's a little bit heavy and to lay there waiting for what seems like forever is a little frustrating. The monitor is good about showing what phase of your cycle you are in and calculating your personal coverline based on your temperatures, but to get the clearest picture of how your temperatures fluctuate, you really need to put the temperatures on a chart. I called to ask about the software to plug this into the computer and download the temps but the company told me it was very expensive (hundreds of $$s) and that you don't need it. That was a little frustrating but I found a great website online that will create a perfect chart (and analyze it) for you simply by inputting the data from the monitor ( [....]). Since the monitor stores all the data you need for 6 months, charting is quick and easy to do whenever you have time (you don't have to worry about inputting it every single day). Overall, I recommend the BBT method and this particular themometer. It is a little pricey but way less expensive than the ovulation tests and other monitors that require testing sticks, etc. If you use this for 2 months, it will be cheaper than most other products out there.

I wish I had known about this device before I purchased the BabyComp fertility monitor for over $500.00!

This does the exact same thing as BabyComp but is obviously much cheaper and is infinitely smaller and lighter and much more user and travel-friendly.

You know when to expect your period, when you're fertile, etc.

I personally like seeing my temps on a chart, so I enter them daily on FertilityFriend.com and that way I can see ovulation dip, possible pregnancy, etc. There are scores of Fertility Awareness sites out there that are free and easy - Fertility Friend is just one that I happen to use.
I also use the "My Days" and "WomanLog" apps on my Droid.
What can I say? I love temping.
;)

Love the fact that it's got an alarm. I usually don't even wake up fully - I just reach over, grab the device, temp, and I'm done. There's a beep that lets you know when your temp is done and recorded.
Yes, it's a bit heavier than a regular, non-computing, non-period alerting, non-ovulation alerting $5 thermomter, but it's not "heavy" by any stretch of the imagination and it's SO worth it. I really love this little thing and I love knowing my body well enough to know exactly the day my period's coming, exactly the days I'm fertile, etc.
Fertility Awareness is effective, natural, and won't increase your risk of cancer and stroke like The Pill.
And frankly, women SHOULD be in tune with their bodies enough to embrace Fertility Awareness.

Anyone want to buy a slightly used BabyComp?

I have read a couple of review for this device and do not agree with the lower ratings. Firstly, the alarm can be switched off. Read the instructions (the 12am has two settings, 12 am ON and OFF). Secondly, the device takes the full 3minutes to read temperatures, which is adviced by all serious FAM methods. I know that the LadyComp does it faster, that does not mean the LC does a better reading, it is rather the other way around. Then, I found many instructions in English online from the manufacturing company. So, there are alternatives if the one that comes with it does not suit you.
If you want to do FAM this is a good first start, get TCOYF or Nofzinger's book and you are good to go.
The reasons why I did not give five stars is that for a total FAM novice using a device might be confusing. You would be much better off with an ordinary thermometer to learn the rules properly before you blindly trust a computer. Then, this device does not require that you enter your CM, which means it is not truely FAM, but temperature only. And it also does not like if you enter CM after your peak.
Mainly though, I find it is too expensive here. I got it for a third of the price from the manufacturing company.

Starting using this with natural birth planning. Great because I could set the alarm early, take my temp and fall right back to sleep, it stores your temp so you don't have to wake up and write it down. Battery lasts long. Discrete, quiet beeps, never woke my hubby. Great to also store memos. A must with natural planning!

Others have commented that the software to connect this device to a computer is nonexistent or very expensive. Here's how I did it. (Note that while the product appears identical, I'm not sure that the "Optimus" version available on Amazon is exactly the same as the one from Craig Medical, so no guarantees that this will work for you.)

1. Software and USB cables are available from Craig Medical (just Google "Craig Medical Sophia") for $55. They will send you a USB cable to connect it to your computer and "Madonna" software on a CD. The USB drivers only support Windows 98 and 2000, so if you have an old machine with one of these operating systems you should be good to go. If not, see step 2.

2. The device is manufactured by Nishitomo in Japan, which produces a whole line of Sophia fertility monitors for the Japanese market. For whatever reason, they have stopped producing export versions of the software, but the latest Japanese version is available for free. It runs on all modern versions of Windows (including 64 bit) but there is no Mac version. To find it, Google "madonnav270jpn" and you should see a single result. The page is entirely in Japanese, but the download link is at the very bottom (6.01MB).

3. Installing the software is a bit of a guessing game if (like me) you don't know Japanese, but there are only about three steps and if you accidentally click "cancel", try again. At the first screen, option 1 installs the program and option 2 installs the USB drivers. You need both.

4. The CD from Craig Medical contains a user manual for the older English version (2.30). All of the menu commands and window options are in exactly the same place in the current Japanese version, so you can use the manual to figure things out.
