Basal Body Thermometer
I really liked this thermometer because it is fast and easy to use—you get a temperature reading in just a few seconds. The display is large and clear, so it is easy to read without any issues, even at night. I have used it both to check for fever and for ovulation tracking, and it works very well; it feels accurate and reliable. Furthermore, the material is comfortable and practical for either oral or rectal use, and the fever alarm is a nice added bonus. Overall, it is a simple yet high-quality product that delivers on its promises

Great value thermometer
Nice thermometer. Big display. Accurate temperature readings. Settings are easy to change. And a nice case to keep It in for storage. Great value. Plus, a lifetime replacement warranty from Boncare that comes with the package. That is great.

Precise, fast and very easy to use
The screen is large and clear, which makes it much easier to read the temperature. I also like it because it has a fever alarm. It is comfortable to use and cleaning is easy. In addition, it is light and easy to store or take on a trip. In general, it is an excellent option if you are looking for something reliable, practical and multifunctional. Very good value for money

PLEASE GET IT I LOVED IT
I loved it, I got it for my TTC journey and it’s worked amazing! It’s very easy to use and comes with a light that tells you if it to high or if it’s good. Also it’s very cheap. You can adjust everything to be what you need it to look for

Good product for price, wish display stay lit throughout for easier visibility
Had this for a week and been using daily for BBT checks. It seems to read temps well and fast (often 2-5 seconds). However, the display goes dark after it shows the previous temp so in the dimness of a morning bedroom, you can't see when it goes to "Lo" (typically when it's ready to be used). The screen also stays dark while it's reading so you can't see the temp change. Only after it beeps (a few, reasonably quiet beeps) does the display light up again so you can read the final temp. Since I use this in the morning, before turning on a light, I do wish the display was better lit. The large display does feel like it balances differently than the usual thin thermometers, but it's fine for me.

Thermometer!
The item arrived on time. The item is described as it is and work well. The item can be either used orally or under the arm peat, but switching buttons (instructions are with it). The item measures body temperature (BBT). The item can be used either for just tracking temperature or for some women who are tracking their cycles or working on become pregnant. The item can be used with an app (Premom) or by itself. The item has versatility, which is nice. The item comes in a plastic case that holds the thermometer. When measuring the BBT, it specifically show the temperature. Not bad at all! The item is not expensive and the window of the thermometer displays clear result(s). The thermometer is not big, so it can be stored in smaller places.
