I am amazed. Jai tested the effectiveness of this device with 2 other thermometer and this one gives me the exact temperature at 0.2 degree. I was surprised by the small size of this device.
Of the three ordered and received (very fast and smooth as always with Amazon) only two were working. A day later, one and two were still working HS. It is not very expensive but it's true nevertheless I expect a little better for the price.
I have 7 and I have to make a calibration test ... well ... 0.1 degree difference between devices, thermometers 7, it is rather very much good, I like, and put five stars. Yippee!
