I bought a coverstar 4 years ago, 20 x 44. So far it's been great. It's the one with the aluminum cover, not integrated into the coping, but has a track that runs on top of the cement deck right next to the coping. I leave the top on all winter long. Just make sure that you leave a lot of water in the pool before it freezes. My lines are blown out, antifreeze put in, and capped so that the water can remain high in pool. Every spring when I open up, instant perfect pool. The water needs to be left high so that the cover can rest on it all winter long without getting stretched or broken.
