Title: Not bad for the price
Review: I ordered two of these. They display a one degree F difference between them and are one and two degrees F above my more expensive thermometers. I can't swear to the accuracy of any of them. I picked one to mount over an A/C vent to monitor my A/C efficiency. I put the other on my shop wall. The mounting was easy and quick. You must pry off a little part with a hole in it and screw it to the wall with the enclosed screw. Then fit the thermometer back onto it. For the price, they are a good buy.
