#edit: After I inserted the new battery, and first had hinbiegen the contacts so that they make contact and the thermometer will not turn off when the battery compartment is closed runs it now. Unfortunately, it jumps in the water happy times by 1-2 degrees around and in the air there is a degree more than the good old mercury thermometers.
By the inaccuracy and poor contact condition of the battery remains for me nothing more than to go to 1 star down and discouraged from buying. Dear temperature just prefer to be probably comes out to the same thing.
Or simply to invest more in a functional product. Since it is only an approximate guideline at the temperature at me I can thank God so that life nevertheless no longer the same product would buy If something goes completely broken.
