## Questions & Answers

**Q: How do get temperature down to start.**
A: Hi Betty! I sure hope you are doing well🙌🏼🙌🏼 So what you dobis hold the thermometer at the end, not the end you put un your mouth, and shake it really hard downwards. Make sure you have a good grip cause youll end up tossing it otherwise or you can sinply run it under cold water. I hope this helps Betty! God bless you and I hope all is well.

**Q: How do i get it to work how do I get it to go past 98.**
A: If you do not have a temp it will not get higher in temperature. So thats a good sign. Otherwise it might be broken.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Reliable
*by  on Reviewed in the United States January 10, 2025*

Digital thermometers don't work well for me. With a glass one I get reliable readings.

### ⭐ BUYER BEWARE
*by  on Reviewed in the United States October 16, 2025*

This item is nonreturnable because it is a medical item and ours DID NOT work. My husband is in the medical field and he knows how to shake down mercury thermometers. But this one would not shake down. He hurt his arm trying. I went back to the reviews and saw that many people are having this problem. I can't believe with this many having this problem that this company is STILL selling this product. But it is no loss for them because they are non-returnable so they make a profit regardless. Horrible company for doing this. And Amazon should not be allowing them to sell with this many negative reviews.

### ⭐⭐⭐⭐⭐ Will never use digital thermometers again
*by  on Reviewed in the United States January 8, 2023*

I have two of these and four digital thermometers. I decided to test them against one another. The digital thermometers were all over the map with readings, but these two always matched. I set a timer for 10 mins for these. The digitals beeped anywhere from about 6 seconds to 1 minute depending on the brand and varied as much as 1 degree from each other. More convenient perhaps, but not worth sacrificing accuracy.
