Well made
Well made and stack well. I bought one, then I got three more. I now have four of them. They would be a little bit expensive without the discount I had. The DVD had the exercise of standing and switching handles with rotation. That is a novel use that I had not thought of before and good for training coordination under some load. I would also like to learn more about use of the BOSU back with the risers for senior citizen workouts.
