## Questions & Answers

**Q: Where is this thermometer made?**
A: It says made in China on the bottom of the box.

**Q: what type of battery does this use?**
A: From the directions:  Alkaline manganese battery, type LR41, 1.5 V service life; minimum 100 hours under continuous operation.

**Q: Can the thermometer be used to measure temperature via the under arms for basal temp readings?**
A: Hi Amazon Customer,

Yes, you can. However, we do not recommend it since accuracy is very important in measuring the basal temperature. Using axillary method will only measure the skin or surface temperature and it is often affected by several factors, such as room temperature.

Because of this, we recommend using the more accurate methods, which are orally or vaginally/rectally.

**Q: Hello, how do I recall a temperature?**
A: Hi Renee,

To recall the last measurement, the thermometer should be turned off, then press and hold down the button for 4 seconds or until the word "LAST" is displayed on the screen. Once the button is released, the last measurement will be displayed.

Hope this helps.

    Great product
  

*by T***D on Reviewed in the United States on October 13, 2019*

This is a great product! It is very quiet when I use it. I don’t wake my husband up when it beeps. It is very accurate and it has nice colors. I highly recommend this to women who are TtC or trying to prevent pregnancy. This is a great product!

    Ordered this because all of the thermometers were out of stock everywhere
  

*by P***R on Reviewed in the United States on March 28, 2020*

My old thermometer didn't register temperature for some reason.  I checked it when the COVID19 situation started.  I tried to find one like everyone else and had no luck.  Then I remembered another way to go-the basal thermometer. It should be very precise.  I fortunately have not had to use it yet, but considering that I have nothing else, the fact that it turned on is a plus!

### ⭐ 1.0 out of 5 stars







  
  
    Difficult to access the last temperature reading.
  

*by A***Y on Reviewed in the United States on December 4, 2019*

This thermometer is accurate but difficult to use. It is very inexpensive and I found mostly good reviews about it, however the quality matches its price. I have to press the button really hard to turn it on and off and to get the last temperature reading I have to hold the button down for 3 seconds. However this is impossible most of the time since the button is so difficult, it just turns on or off a bunch of times. Only if I'm lucky it will actually work. Maybe I just got a messed up one and the others are better. I will be returning it though and I don't reccomend buying this thermometer.
