Very accurate instant read thermometer. I have had other thermometers in the past; however, this one has shown its worth in quality of action and build. I actually left it out in heavy rain overnight. It continues to work perfectly. I also enjoy the purple color.

Great Upgrade!
Previously I owned an inexpensive thermometer bought from a large online retailer. It was adequate, but the Thermapen One is both far faster and more accurate. Very glad I got it on sale!

So far, the thermometer has worked great. Readings are very fast, accurate, and it's easy to use. The thermometer will go to sleep if you set it down, but instantly wakes back up when you pick it up, making it easy to use continuously without worrying about turning it on/off.
