Title: What were they thinking?
Review: This unit and the essentially similar Vigoro Automatic Yard Watering Kit have one major flaw. The only adjustment you can make to the zones is the watering duration. In other words, you cannot make one zone water at one time and another zone water at another time. All zones come on at the same time. That sort of defeats the purpose of having zones, doesn't it? The only way I can see this device being useful to anyone is if you want all the zones to come on at once, and want one to water for ten minutes and say another water for say 5 minutes. That you can do. In my case, I can't have all the zones running at once or I do not get enough water pressure for the sprinklers to work properly, but there is no way to make one zone run at one time and the another zone to run at a different time. Of course they don't tell you this on the packaging, so you have to waste half a day buying it, trying to make it work and then returning it to the store where you bought it.
