Bests & Worsts Reviews from Amazon

So far, works as advertised. Only issue was that some valves were stuck open, as others have found. Struggled a for a while then sent a message via Melnor website. No answer. No phone # for technical assistance on website or instruction manual😡 Then my wife found in small print on the package this # 877-283-0697. Short wait and a nice woman told me the solution. Turn off the timer, press manual, choose which zone, and set 1 minute on time. Valve opens, then closes and all is good. Repeat for all stuck zones. Don’t know why there is a ‘hidden’ phone # and some instructions about this issue as it’s clear they knew about it. So one star off for this hassle.
