Product review (1 stars): Avoid this item, it's VERY inaccurate!
The unit is so inaccurate it's not even funny, you'd be better off just guessing rather than using this device. The two pictures were taken about 10 minutes apart, the temperature was reading -35, then it was reading 157. I know it was cheap and I wasn't expecting it to be up to NASA standards... but it's ridiculous. There's plenty of other options out there, I would avoid this one! Also be aware that you cannot return this item through Amazon, it has to be returned directly to the seller at your expense for a refund!
