The only thing that bothered me: my long hair very much caught in the upper part of the bracket where the rails on one another, especially during insertion and removal, because movement if and only comes into the rails and hair then just like to suck and hold leave. My hotfix: rails fixed with duct tape in my head size ado, that solves the problem and makes the hair on and taking off a lot more comfortable, because the size is always correct the same. Is annoying, but for me no reason to deduct points.
Price-performance incomparable, never seen better!
