I bought a used Rainbird ESP Controller off of eBay last winter. When I received it in the mail, it had a custom made sticker attached to the outside of the front door to the controller. It was made of silver foil and read something like; System Installed on _______ by L&L Irrigation Systems, Inc. (555) 555-1212 I thought that was a pretty clever idea. Around here, people are always moving. And I am sure the person we installed the irrigation system probably didn't mention when they were selling the house, "Oh, by the way. Lewis Landscape Services installed the irrigation system back in 1999. They're great. Here's their card in case you ever have any problems with the system." So I was thinking of making my own custom sticker like that to put on each timer with every new irrigation system. Then, if the house ever gets sold, the new owners would instantly think of our company if it ever needed to be serviced. Any of you guys do this? Do you think it's a good idea? If you do, and decide you want to use it, you gotta pay me $100.00 for clueing you into the idea.
