Pro: Excellent design concept. Works well, once you get it working correctly.Cons: Pentair is very short* on product details and technical specifications. Still a good product so long as you check out what you are doing with Pentair tech support.*seems to be S.O.P with the major pool equipment manufactures like Pentair and Hayward.
