Indo boards

hey i just got an indo board several weeks ago to help improve my balance during the off season (considering I haven't been able to get a cold water wetsuit yet and gear) and was just wondering if anyone else here uses them. I got the original indo and so far its pretty sick. I spend unhealthy amounts of time on that thing, walking the board, doing shuv its and just screwing around in general. It seems like its all its cracked up to be.
