Title: Durable, nothing to complain about, smell goes away
Review: Function:I mostly use this as a chair, though this involves putting more regular pressure on it than most people buying for exercise, so I think that's a good test of its resilience. I've had no problems after a couple months. The pump works fine and is easy enough to use.Smell:It smells strongly when you first unpackage it, but once you leave it pumped up for a few days, that goes away completely. Don't try to wash it off like some reviewers--it's not going to give you cancer, and washing it will probably reduce its durability, because that smell probably comes from a coating that the ball absorbs when it expands (I don't have a strong chemistry background, so I'm just speculating, but it makes enough sense).
