Had two zones out of six with bad wires; the device solved by issue without having to find and dig out wires to repair. Whew!

Easy to install, I used it because some of the control wires had gone bad somewhere building and the valve box. The device worked perfectly because we still had enough of the correct wires that were good that allowed for this situation.

Response to Slawomir Jurkowski's post. A possible reason to skip a zone number. When two zones are connected at the controller with one wire, the Doubler can't tell when the voltage from one zone quits and the other zone starts unless there is a break in time between the two events which the Doubler will see as a ON then OFF then back ON voltage. For example, some controllers may switch the voltage from one zone to another very quickly, so the voltage would appear to be constant. Skipping a zone provides a long time interval so the Doubler can detect it and switch over to the other valve in the sequence. This would also explain why the Doubler needs to complete the entire sequence to get back to the starting zone.

The description doesn't make it clear, but you have to run the 4 valves in series each time you want to water any one of them. So in one sense they are not independently run. For example if you add 4 zones to a place where you have one zone and number the zones 1 - 4, You would have to run zones 1 - 4 every time you water. If you only want to water one of those 4 zones, you would have to turn on each of the other 3 to keep the unit in sync for whatever is the shortest duration on your controller, otherwise the next time you try to water, the wrong zone will turn on. Additionally the manual says you have to skip a zone between each one on your sprinkler controller if it is solid state (means electronic which most of us have). So if you want to add 4 zones after zone 6..according to the instructions you would have to use the wire terminal on your sprinkler controller for zone 7, zone 9, zone 11, zone 13. I'm not sure why this is and i haven't tested it without skipping zones. But this is what the instructions state very clearly. I'm sending mine back and am going to run additional wire so i can actually get truly independent zones.
