So tell me the difference between contractor 1804 and HD 1804 besides the goofy sticker on the side and the 15' nozzle. How bout the dv100 valve? besides the gray plastic instead of black. Tell me why rainbird can't come up with a decent remote for their esp controllers. How about a wireless rainsensor? They copied Hunter on there rotor. Claim raincurtain technology but I have yet to see any precipitation curves on their 5000s and I have asked. Copied MP rotator (unsuccessfully IMO). What are they doing on the ET front? And wasn't Hunter the first to come out modular? Seems like rainbird is resting on their haunches and relying on their name instead of doing anything groundbreaking. Then when they do copy something it fails a few times. By the way, take a wild guess what my "best product" is. Give me a reason to go the other way.
