Product review (3 stars): not bad for the price
Mine was missing the battery that was supposed to be "include" according to the description. Seller refunded me a buck. Cool! I have two of these. When the battery starts to fade, the display gets hard to read from any angle other than head on. Just get a lithium coin cell and forget it for the next five years. The accuracy is within +/- 1 degree or so, which is perfectly acceptable for the price. It's a panel mount type which is nice for the nerds out there. Probe is decently long. Changing to Fahrenheit is pretty easy as long as you have excellent vision, a steady hand, and a sharply pointed soldering iron. Just put a blob of solder across the two lonely horizontal pads and it'll display F.
