Iv'e owned them and I really like them . Somebody liked them better than me and that was it . I'm going to get some more . I try to have a little of all , ball type , tube , different sizes too , you never know when you might raft . Some things I like about them, like you say little space taken , and when sailing they lay flat on deck , also they make nice knee pads . Dislike , at anchor or a mooring when it's windy they rattle on the side of the boat .
