Even after calling in to have a customer service representative look over my cart I still purchased a rain sensor that does not work with my irrigation kit. This is unacceptable customer service. I am now forced to return the rain sensor, or ship my entire kit back. Since "this item is a kit" I am not able to swap out the correct timer that will work with this sensor. The fact that these two items can ship together simply shows that Dripworks as a distributor is not able to verify that components packaged together work as a unit.
