This company is unbelievable. I can get no one on the phone. I can't set the sprinkler because it waters all night, rain or shine. I tried going online to view the demonstration, nothing they explained appears on the screen. I have had sprinklers before and all I had to do was set the time of day, number of minutes and frequency. This stupid company expects you to do everyday individually and I cannot even read what's on the screen. I can only operate this system manually so when I go on vacation, I have to choose between no water or water all day. I might add the cost of water is very expensive in my area. I will never ever purchase anything from this company again. STUPID!!!!
