Good device. Fairly accurately measures the temperature. It is necessary, of course, to change the coefficient for different materials. Sent quickly, went fast too. Seller recommend

It was about a month before black earth. It's been a long time at customs. But the goods are OK. The only thing is unclear, the viewing angles are strange. From above-from below is normal, on the left is normal, on the right is not visible. It is powered by 2 AAA, they are not included. Compact, I expected that there would be more. There are no buttons on, it wakes up from the temperature measurement button. Turns off himself.

For measurement in pizza oven Works very well The measurement seems accurate Manual in Chinese only, the way to get the English manual does not give anything. Probably does not exist in English, even less in French. But it's simple enough to get away with it.
