Easy to use and reliable (2009-05-18)
I bought this thermometer based on the Amazon reviews. After two weeks of daily use, I think it works perfectly. The beep is quiet enough that it doesn't wake my husband in the morning, and it's easy enough to use that I don't even really fully wake up -- I sort of blindly grope on the nightstand, find it, stick it under my tongue, push the button, and a few beeps later it's done. I can then push the button again later to see my last temp and write it down. Pushing the button doesn't clear the memory, only taking a new temperature does. Good product.

this is a necessity for anyone tracking basal temperatures for fertility planning. very reliable and sensitive to slight changes in temperature.

sometimes works; sometimes doesn't. i have questions about its accuracy, as well - midday temperatures taken five minutes apart show nearly a degree of difference.

useful in that you can take your temp and go back to sleep, then check the readout later; however, for accuracy there are likely better products out there.

Simply does not tell correct temperature (2009-03-29)
I'll keep this review short, simple and to the point. The thermometer consistently reads my temperature (and my girlfriend's temperature) at 96 or 97 degrees. Either we're almost dead, or this thing doesn't work. It never registered normally, not even once. We each tried it a dozen times, both with the covers and without, and got the same result either way.

As for the reason for two stars instead of one: it is easy to use.

Not Great (2009-03-11)
I bought this thermometer for ovulation charting because it was supposed to be the "best". I had been using a CVS brand thermometer that was accurate but took FOREVER to get a reading. So I was really looking forward to the quick readings this one promised. Alas - here's the breakdown:

The Good: It beeps every 4 seconds so long as you have it in the right spot in your mouth. If the consistent beeping stops, you've opened your mouth or moved it so you know you need to turn it off and start over. I like this feature at 6AM when I'm half asleep and have the tendency to fall asleep and move the thermometer. The beeps don't bother my husband, but he is a hard sleeper. It also has an amazingly quick read-out time. It takes under a minute if you have it in the right spot.


The Bad: The accuracy is poor. It only has a readout to 1 decimal place (most basal thermometers have 2). It has also been giving me wildly erratic readings. I've been charting for years so I'm pretty diligent about doing it first thing in the morning, at the same time, without moving. There's nothing that should be causing such erratic temperatures, especially when the beeps are indicating that I'm holding it correctly. I don't know if I just got a defective one or what.

Summary: If it's not accurate, it's worthless, so I'm going back to my old SLOW thermometer :-( I was so excited about this too.
