Review: Works well, just don't let it get wet - Accurate, easy to use, and good price. Just don't let it get wet -- I accidentally dropped mine in some water and now it gives false high readings 1/10 of the time (I still use it, I just take multiple readings and know that the result I get 9/10 times is the accurate one, but that 10th time it will show me something ridiculous like 20F degrees higher than i KNOW it is.) I'm still making it work but be more careful than I was!
Review: Great and economical thermometer totally recommend! - Great little thermometer! Came with the aaa batteries needed to use it, installed in a snap( no tiny screws to deal with) I was worried it would be as good as the more expensive models but it works great! I bought this to test temps on my garden plants to ensure I am using the right amount of shade fabric. I have it a try in the house and I was surprised by how quickly the reading changed, no delay, just reading temps with my movement. I will be using this for cooking, ensuring pavement is not to hot to walk my tenants dogs, and my daughter is thinking up all the experiments she can use it for. I am very pleased with my purchase. Ps. The kitten is also please by the bright red dot lol

## Questions & Answers

**Q: Epoxy resin temp?**
A: If it gives of a "heat-signature" it will show you a close approximation of what the temperature is. I use mine to find out the surface temps on my griddle when I adjust the gas knobs.

**Q: Is it good for checking wall temperatures to check insulation needs and results of insulating?**
A: I haven't used it for that particular reason but I think it would work.  My main reason for purchasing was because I own a Blackstone Griddle and wanted to know the different temps on the grill top.
I have however used it to measure the heat on the outside of my brick house.  In the summer the sun shines directly on the front brick and it gets very hot to the touch. I have directed it at my inside walls also and it gives a temp. I have been very happy with my purchase and I think you would be also.

**Q: Can you turn off the annoying beep?**
A: Sorry, this cannot close the beep sound，，This measurement accuracy is good, has been used for 2 years of records, and is still normal use

**Q: Can you use this to check the temperature for candy making?**
A: This is really more of a surface thermometer.  For candy making, if the temperature is homogenous it could work.  I've found that that temperatures can vary significantly from the surface to the bottom, so I prefer to use a thermometer inserted into the product.

### ⭐⭐⭐⭐⭐ Works well, just don't let it get wet
*by A***E on July 22, 2023*

Accurate, easy to use, and good price. Just don't let it get wet -- I accidentally dropped mine in some water and now it gives false high readings 1/10 of the time (I still use it, I just take multiple readings and know that the result I get 9/10 times is the accurate one, but that 10th time it will show me something ridiculous like 20F degrees higher than i KNOW it is.) I'm still making it work but be more careful than I was!

### ⭐⭐⭐⭐ Good tool especially at the price
*by S***S on February 13, 2021*

Pros: cheap, fairly accurate, easy to use, live reading for scanning, comes with batteries, turns off itself so preserves battery life Cons: beeps after reading Definitely worth the money so far. I don't know how accurate it is on the higher end of the scale, but calibrating with ice water it was at -0.5C instead of 0C, but accurate enough for my purposes. The emmisivity is adjustable, but haven't bothered with it. They give a little chart for the materials you'd need to adjust for (aluminum, glass, etc...) If you want to do that though.
