Query: Great Concept Bad Design

This is my first review, i guess i am selfish that way because i sure read them. Anyway, this product works great but only for about one season if you are lucky. the moisture gets into the motor area and ruins it, especially if you keep your pool elevated in chlorine, it eats away at the seal and oring on the screw in on/off button. if you must have it then make sure you find spare seals and orings for the screw in on/off button. if you look hard you might find them at a hardware store cheap no need to buy the entire switch/button its expensive. Te keep it short do not buy this item unless you can be extra careful, I almost bought another but read through enough reviews to find out it has crapped out on too many people for this same reason. Maybe a review section thats exclusive for "after one year of ownership" would be very insightful.
