We chose to measure the humidity and temperature of the room of our future baby. Unfortunately, we found that the temperature was not correct: with another thermometer, there was a difference of + 3/4 ° C, which is huge! Maybe it was a defective product: anyway, we returned the article. Too bad because the design is very nice and also the display (the little smiley lets say if the humidity is correct). We will instead turn to a recognized brand product: [[ASIN: B005G6CLKA Oregon - EW 102 - NGA1021010318001 - Thermo Hygro Wide Screen]. It is certainly more expensive (more than double) but many friends advised us this brand: to see.
