To be fair this is my first shoulder rest, opting to go with something a bit more costly than the cheaper alternatives so i cannot say if that really gives much in sense of performance, but i can say that this shoulder rest does a great job. It is very adjustable in angles and height. It sits very well on my sholder and does not move around at all once attached.
It also looks stunning, which is one of the reasons i chose it in the first place. The material may not be as amazing as looks make it seem, but still worth it, looks new after 6 months use.
