Bests & Worsts Reviews from Amazon

I pulled the unit from the package, connected the battery, and pointed the laser at my wood bar. The temperature was 90 deg F? The house was 68 deg F and the bar was cool to the touch. I proceeded to check other objects with a similar outcome. I then went into the kitchen where I had a pan of boiling pasta sauce, it read 210 deg F. Therefore, I’m not sure if it works or not? This product is junk. It’s 65 deg f I’m my house; leather chair reads 92, wall 96, speaker that is off 95, metal leg of chair 95. Enough said. I’m returning for a refund.
