We have one. I like the closure system, it's comfortable on the back of the knee compared to other designs, and cinches in securely if you do it right (took a bit of practice). However, the rubber was not thick or sticky enough for my tastes and I would often ditch it in favour of a send pad. I have now sewn an extra layer of rubber on and it's performing much better. I'd say it is a good pad for the price, but send pads are definitely more useful for advanced kneebars if you can afford them.
