We purchased, as an add on to the BONGO Board and the Extreme balance board pro, after being exposed to them at a rehab clinic for a member of the family. We thought having a balance aid would be a good idea for us as new users of your products. Turns out we have not used them for as long or as often as I thought might be needed but they still get used by guests or when we do our cool downs to ensure safe mount and dismount. They are well suited to the boards as they offer enough support to mount or regain stability.
