Anyone use thier products and if so,what do you think of them? Yesterday I was at my supplier.I told him that in the fall,I was going to install an irrigation system at my house and that I wanted a price on Hunter I-20's with the SS riser. Do you know he tried to talk me out of the I-20's? He wanted to sell me K-Rain rotors.He said they are identical to PGP's. Anyway he brought one out and they just looked really crappy to me,and I am not even in the irrigation business. The price was almost one third the cost of the Hunter SS I-20 rotor. I am not going to use K-rain but was just curious as to your input on them. Thanks!
