Wondfo Digital Basal Thermometer for Women Fertility – BBT Thermometer for Ovulation & Pregnancy Tracking – High Accuracy & LCD Display & Waterproof

Got this to better temp myself in pregnancy, and will also be great to get a more exact temp which I'd like to do for other reasons later on.

Came with a “low” battery message and barely working. Shouldn’t come dead. Will be reaching out to customer service and update review.

faily basic, I'm not sure how accurate this is. I would just use this as a basic thermometer but even with that not having a backlight really makes this very difficult to recommend

The digital thermometer has a soft lavender color and comes in a clear case with a manual. When I turned it on, it showed me the temperature in Celsius and I didn't find in the manual how to switch to Fahrenheit. But on Amazon, it says to hold the power button until it changes to Fahrenheit. It has a flexible tip and it measures my body temperature within minutes. In the manual I learned I can use it orally, rectally and in my armpit. I only use the latter method. On the back of the thermometer I read it's made in China and manufactured on December 15, 2024. It has an IP22 ingress protection rating. In the manual, I see it's distributed by Wondfo USA Co. Ltd. in Bolingbrook, Illinois. It lists an address, phone and a website. I removed the battery cover and I see it uses a small LR41 button battery and according to the manual, its expected service life is about three years.
