Review: Durability - Over a year of use, the product has proven itself excellent. It works reliably and flawlessly.
Review: Works great. IR Thermometer is Invaluable Bonus - This is one of those tools that I couldn't quite justify buying for a while. But now that I own it, I use it plenty often. It wouldn't be my first addition to a toolbox, but once you've established a good baseline, it's a nice, small one to add. It does not have a light on it. I assumed incorrectly that it would. I use the temperature gun very frequently. Some uses: - Diagnose poor house insulation - Figure out the coldest parts of the fridge (important for getting optimal meat storage). - Lots of uses when cooking. Note: temperature range is limited compared to a full fledged IR heat gun. Also, be aware that a material's emissivity can throw off temperature readings (beware of shiny stuff mainly).

## Questions & Answers

**Q: Has Klein fixed the battery cap issue as of Jan 2020 yet ?**
A: I buyed in 2019 and I didn't have any issue with battery cap.

**Q: How long does the Temp reading stay displayed? Only when you push the button, or does it hold for a few seconds?**
A: It stays "on" for a few seconds

**Q: Can it tell the difference between a hot and neutral wire, say when you open up a light switch?**
A: Neutrals. When wiring lighting circuits supplied by a grounded general-purpose branch circuit, the 2011 NEC now requires you to provide a neutral conductor at nearly every switch point [404.2(C)]. The purpose for this is to complete a circuit path for electronic lighting control devices, such as occupancy sensors.

**Q: What temperature range will it read?**
A: Spec's list Temp Range as :  -22 - 482 degrees Fahrenheit.
