As expected, this is an economy model & smaller than the rectangular wooden board used in physical therapy. Still, it was low cost & allows me to work on strengthen my ankle range of motion after surgery. Even after a few weeks' use, I can still balance much better on the board at my therapist, so I think the larger board would be more beneficial and less frustrating. A fair price for an item I hope to use for a short time. If I had to use it every day, indefinitely, I would have upgraded to a better board.
