I like it. The pump works great, though it is a bit tricky to figure out at first. It fits back in it's case without having to force it. The material is comfortable enough to sleep on by itself ( I know this because my sleeping back kept sliding off it and I was sliding out of my sleeping bag). The only thing I didn't like is that it wasn't grippy enough, but I suppose I shouldn't expect too much in that area since my sleeping bag is so slick.
