Yet unlike our model, it is not as portable. It fits in the trunk of a car and can easily be brought to competitions and demonstrations. Our school would not be able to use this board holder since our dojang's structure doesn't allow for a hanging bag. It is hard to compare stability without seeing this machine in action. Like all the other models, this model is great for protection of the board holder's fingers.
Stability is questionable.
It takes a pyramid of several men to hold a 5 to 6 board break without floor or heavy bag support. Holders can be men, women or teenagers. We like this idea too, and again - bravo to the designer. If you've been training for 20 to 30 years plus, than no doubt you've seen this machine. You may have even used it before.
