I love this style chin rest that allows your chin to be cupped in the more natural position (in my opinion) closer to the middle of the instrument. The Guarneri and Stradivari style ones I feel like most people, myself included, basically rest their chin/jaw on the arched part that goes over the tailpiece, rather than in the actual cup on the side. The quality of these Gotz ones seems pretty good, but it’s nothing to marvel at. Simple and great for the price.
