I bought mine at Lowes. My solenoids would go bad all the time, I RMA'd them so much that the factory stopped responding to my emails. THe unit that I purchased also had a known problem with the diaphragms so I would have to get replacements every summer to fix the known issue. Eventually my warranty was dead and I just went out to fire it up again and all the joints leak, the diaphragms leak, another bad solenoid. I think Rain bird for replacements? and I am going to glue together my own manifold. Dont buy this because you think its easier. I did and I want to punch myself in the face. Good luck with any other item, you cant go wrong unless you buy this one.AS for as the buyers listing it, I dont have anything against them, jut the item.
