        I do like the simplicity of the ovulation test strips.

        It works, very precise for replacing the cheap chinesse thermometers

        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.

        Great, consistent and accurate thermometer - BUT...

        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!

        Good day!

        I just saw your review and it is clear that we failed to meet your expectations.

        I truly apologize about this. I’d love it if you would give me the opportunity to make it right with you.
