Seems to be a good brace for the price. I've had it now for 6 m. Has held up good but the decals came off. Fits well and hardly knows its there. As far as performance goes I have no idean nor do I want to find out. Io
If we were to describe the all new R4 in one word, it would be WOW! This is definitely one for the masses because it's easy to use, comfortable and affordable for everyone.
