As with other reviews, the battery was dead and with me already in the supply. For a batch number with 01/09 I would have expected, the current would be 2 month later yet. But the real reason for return was the temperature measurement. The thermometer was compared with a "old-fashioned" mercury thermometers to a full degree lower. In principle, the product is a good idea, but in this accuracy I would NOT recommend. Here would be mentioned that though it has a CE mark, but otherwise no seal what Dan makes me even more suspicious of the measured values.
