Microlife Digital Basal Thermometer 1/100th Accurate, Fertility Prediction and Ovulation Tracking, Oral or Vaginal BBT, (60-Second Reading),

Worked well, easy to use, great price compared to other options I saw.

I use this every day, when i can think of it. I use it 3 times in a row. I am warmer on my right side of tongue than my left, lol. The battery has held out for 2 months now. Once battery wears out, it is time for another. Do not remove battery.

This is just OK. It works fine. My complaint is that compared to another one that I bought, this has hard plastic and it is hard to keep in place. I really have to hold it with my hand to keep it from slipping. The other one I bought on Amazon (Easy@Home brand) is longer and has a softer, somewhat flexible probe that doesn't slip out. Performance-wise it is OK.

Fantastic body basal thermometer! It is fast and accurate. It says it takes up to a minute to measure temperature but it really doesn’t feel like that long to me. Theres one beep at the end and it is not loud; which I like a lot. You can’t go wrong with this purchase!!

I love this. This seems so much more accurate than the quick thermometers. I got it from my mom and she says it works great. I've had the same one for a couple of years and I might get another one myself.

I found there was too much variation if I took several readings in a row. Couldn't get a precise enough number.

This product is perfect. I track my BBT for my cycle & ovulation. It’s the exact thermometer I’ve been looking for. 1/100th of a second recorded & in Fahrenheit.
