I cant believe how snug my violin feels on my body using this amazing accessory! i have no doubt this shoulder rest will eventually beat all the other ones out there. My violin has never felt more stable on my body. I believe this is the stradivarius of shoulder rests! I adjusted for height on both sides, adjusted placement on the violin so it felt comfortable ....and wow, I couldn’t believe how it felt....as if the violin is one with my body. If you want a perfect fit, this is it! Highly recommend this.
