Had a problem with my Kun rest as I must have a weird shoulder. When I had it on my violin, I could put at least two fingers between my chest and the bottom of the shoulder rest so the shoulder rest was doing nothing to support the violin. With this Wolf Forte Secondo Violin Shoulder Rest it is very adjustable and now the shoulder rest is completely on me from the shoulder to my chest. Now need to practice and get used to it. And thanks to Liuba (Oh I hope that's right) for bringing it and a couple of sets of strings to my apartment.
