Cautions: The basal digital is expressly not a contraceptive. It is only possible to measure temperatures that are above the ambient temperature. Hold the thermometer out of the reach of children. Small parts can detach from the thermometer. These can be swallowed by children or cause suffocation by inhalation of the parts. Do not cook, bite, bend, drop or take apart the thermometer. Never open the thermometer except to replace the batteries. Avoid temperature measurements within 30 minutes after exercise, after bathing or eating. Never expose the thermometer in use, in storage or in transit to direct sunlight, moisture, or extreme temperatures; protect the thermometer from dirt.
Prior to use, let the thermometer allow to warm to room temperature when it was stored at substantially lower temperatures. The possibility of allergic reactions and / or skin irritation cannot be completely excluded. Please be careful while measuring to avoid injury. The use of the thermometer is not a substitute for a doctor‘s visit. Clean and disinfect the thermometer before and after every use.

Takes a long while to detect temperature but will worth it when tracking BBT.

Doesn't always beep when done tracking temp so can be frustrating trying to see if it's done the reading while it's still in your mouth.

Takes a while to get use to.

Jessica: a few months ago

This is a great Thermometer for BBT tracking. I agree with others that I wish the back-light would come on when the final temp is achieved. You can make this turn on by holding down the botton until the light comes on but as soon as you stop touching the button it turns off so you have to pay attention. I also think it does take its time when taking your temperature but maybe that is because I am half asleep when this is happening :p

Agree with the other reviewers on backlight. However, works great !

Kristin: a few months ago

I do like the material and soft bendy end, the option for C°/F° and records prev readings (which I've never used). As seen in other reviews the backlight is only on when you initially turn it on it says ok then goes off. I wish it would light up when showing your final temp, in a dark room you always need a light in order to read it.

Katrina: a few months ago

Great thermometer, just wish it would light up when it was finished taking the temperature.

R.J: a few months ago

Great badal thermometer as it was hard to find one anywhere with 2 decimal places. Material is nice and soft too.

Jen: a few months ago

Has a back light and can save up to 10 readings. Does beep when you turn it on and off. I find it takes a while to settle on a reading only issue with it.

Natasha: about a year ago

This comes with thorough instructions and I love that it has a back light, as well as being able to switch from C to F and has a memory.

anita: about a year ago

I got this product with my Complete Control Bundle and it's working amazing. Was very hard to find a basal digital already and the quality of the plastic on this one is really good. It's soft and we use it as our household thermometer too!

SD: about a year ago

Good thermometer and easy to use, however it does take some time to read your temperature.
