Fast delivery. The article of description. A bit expensive anyway just to give temperature and water quantity (moisture). However nice article, very big, readable numbers. You can view the maximum and minimum temperatures recorded. As for Smiley, it seems to work whenever he wants, but that's a detail. Question reliability, sometimes there is a difference of 1 degree temperature and 10% humidity with another device I; Tests carried out in the same place at the same time. But who is telling the truth ???
