Ordered a controller from them but have not received it. Yes, FedEx showed it delivered near door, but it was delivered, we did not receive it. We have surveillance camera on the front of our house and near front door. The cameras capture any motion, no FedEx delivery was made on the afternoon they say it was, and no one delivered a package near our door. Contacted Sprinkler warehouse, they said to wait a day or two, it will show up. After a few days contacted them again, they said they would initiate a trace. After not hearing anything from them for over a week, called them again. They said they have proof it was delivered, we did not received anything and our cameras support this. They have blown us off. Several emails sent during this, not one was ever answered. At this point, they have taken our money but we have not received anything. They do not offer any help. The worst I have every dealt with. I asked to see the proof of delivery they received, I have not received anything. I think they do not have any proof, just SOL from them.
I see other people complain about their customer service, I now have 1st hand experience.
Take your chances, but if you have issues... lots of luck, they will not help.
