Good, but not great… yet
I like the controller, but this app interface is very buggy. I actually came here looking for an update after having this for about a year now, but I see there have been no fixes. I chose the blue spray because it has a delay between zones feature. I wanted it for sprinkler system blow out -run for one minute, wait five minutes for my compressor to re-pressurize, repeat for all 13 zones. I was disappointed I couldn’t do this last fall, am hoping they’d have it fixed by the end of the season. If the delay feature gets fixed, I will give it a five star review
