I have a mesh loop-lock. Gave up on it a few seasons ago. Here in Northeast PA the continuous snow, melt, freeze, snow etc, would weight the thing down so in the late Winter it would be fully frozen in the ice block that is the upper levels of my IG pool. BAH !! My particular situation doesn't require a cover so now I leave the pool uncovered. Not knocking Loop-lock. They are good. Don't have elephants here but I do have other big critters, but the fence keeps them away from the pool.
