Product review (3 stars): The customer service si very good, the first unit arrived defective
The thermometer is very basic and reads Celsius only.  It is not very accurate , the deviation at higher temps is up to 5, at lower temps (room temp) about 1.  The deviation seems to be on the positive side only.
The customer service si very good, the first unit arrived defective, and a short email to the seller was enough to receive a different unit.
