I spent good $$ on a supposed premium one and it ws sone in 3 years. I have a great pool tech and he says that's about all they get, if you take good care of them. Mine was a black and blue one and it was leaving little blue circles all over the pool - the back of the pockets.

So got a much cheaper one this time ($90US), supposedly a "5 year" cover. Much lighter, light blue all over. After installing it on the roller I laughed by ass off when I read the "fine print" of the warranty - "do NOT ROLL" the cover. So for my pro-rated warranty to be good I am supposed to FOLD the damn thing everytime I use it and cover it with the flimsy piece of white plastic. And the plastic is a flat rectangle and the only way to put it on the rolled up cover would be with about 6 bungees.
