iProven BBT-113Ai Basal Thermometer - 0.01 Clinical Accuracy - Ovulation Tracking - Extra Soft Beep - Measure Real Body Temperature

I do like the simplicity of the ovulation test strips.

I bought this thermometer not for basal reading but to have a more precise digital thermometer because most of them shows incorrect readings compared with my mercury cheap thermometer. I bought other brands expecting to have a precise thermometer reading but they worked pretty bad till I bought iProven, I made some tests checking my body temperature more than once and the results were consistent taking in consideration that the body temperature varies but the readings were similar to my mercury termometer.
I really recommend this thermometer to replace the cheap Chinesse digital ones.

Thermometer was great. Consistent / accurate temps. Love that it's two decimal points not one. Love the shape, it's very comfortable in your mouth. I was willing to compensate for the backlit feature because the beep was soft (for my partner still sleeping) and it was getting great reviews for accuracy (which is the most important). BUT THEN... I had it for 2 weeks? And the beep just stopped working. I saw quite a few reviews saying the beep stopped working and thought "oh that's weird. Must be a fluke"... I don' think so.. I think it is a flaw. Unfortunately mine stopped working as well. So now it's not useful at all with no light or beep to tell me it's on or done!

Easy to use. Beeps when finished. Easy to read. Much better than the old shake-down mercury ones.

This was just what I have been wanting for a long time. Precise and accurate temperature, and Quiet beeps that won’t wake half the house like most thermometers I’ve tried. The price is very reasonable too. The only improvement I could recommend is to have back-lighting. But it’s not a big deal because it saves your last temp taken so you can always look at it and record it later. I like that it has the option of Fahrenheit and Celsius as well.
