I order this thermometer. I came within the promised time frame. And then the troubles started... The measuring pin was bent and the thermometer didn't work (it got stuck at 23-24 degrees C). If provided 8-10 pictures and a large video to show that. Tome Store wasn't impressed, kept going on about on a screw that had to be fastened or "assembled again". The nut (!) couldn't be fastened, the device was broken. Tome Store refused to refund. Btw, the photo with the grey background is a photo made after the device arrived at my house, the photo with the brown background in from the resellers page on AE. Can you see the difference and imagine that the mechanical thermometer is broken?
