The displays are easy to read and have exactly only the information that is important to me. The Smiley appears only iff the humidity is right (I think from 40%). For micht specifying the Humidity / Smiley is important because I have the thermometer in the cellar and so also can prevent mold in which I or auxiliary heating entfeuchte accordingly etc. can make time.
Thermometer set automatically. Practically at this point is the plastic flags, which must be pulled out so that the display comes to life.
The thermometer is supplied with a CR2032 - Battery, which are now also very common. Replacing can the Baterrie also quite easy - a coin in sizes between 1 cent and 20 cents is useful to unscrew the battery cover.
Instructions included felt settled in 6-8 languages - but unfortunately is not available in German here. The 'complex' machine but this should be bearable.
