I put the batteries (not included) in bulk (without worrying about the receiver or transmitter order) and it worked on. The screen reads well. The angle of rabatable base is a little too big and if you place it vertically (top refrigerator approximately 1m80 for example) you will lose playing screen sharpness. I particularly regret that the time is not radio controlled but manual. I hope it will remain accurate. Too bad the blow that no date but also water quantity. Models display these details but become too sophisticated. Maxi and mini data personally do not interest me. But considering the price, I maintain that this Temperature meter station (not weather) is worth 5 stars.
