POPKA Basal Body Thermometer - Waterproof, Highly Accurate 1/100th Degree Digital Thermometer for Tracking Ovulation - Fertility Basal Thermometer for Natural Family Planning

This product worked like a charm. I used it every morning to read my BBT to predict ovulation and I’m currently 11 weeks pregnant.

I was a little disappointed with the order by the seller. I bought it as it was on sale. ( big mistake) When I purchased the item-and went to measure my temperature- it beeped and a message appeared Lo which means low battery.I am not sure what the purpose of putting a battery in the product , if it is not a full battery. I would spend your money somewhere else . It’s about the experience not a couple $ battery. If you don’t want a hassle, purchase somewhere else. I have a 2 star as the product actually was in the box.

I wish it had a backlight so I could see it in the dark in the morning. The first reading was very fast but the readings after that took maybe a minute. It was too dark to tell if it was still reading since it took so long to get a reading.

The main problem is that we cannot read the numbers during early morning and midnight.. it is really dark to read the number.. otherwise just ok.

I feel like this wasn’t the most accurate. We have gotten wildly different readings on other thermometers

I used this product only one time. The first time it worked just fine (although the beep was pretty loud and long) and I put it back into the plastic storage container it came with when I was finished. The following morning I went to use it and I was not able to push the button. It stopped working and never came back on. I returned it right away, I need something more reliable.

Pretty disappointed with this product. When I turn it on it always says "lo" which apparently means the room temperature is low but it's 70°F. Took my temperature several different times and days and it always says 95 or 96° which I'm going to say is not accurate. My temperature is always in the 97-99 range and I'm perfectly healthy right now.

Used once then the " lo" appeared. I replaced the battery but it still only reads "lo". When I first turn it on it will read "98.6" then stays on "lo". Also the product received is not what is advertised.
