Great chinrest!
I got this chinrest as a replacement for the one that came with my (used) violin, which was in the center, rather than to the left of the tail. I was nervous about replacing anything, but it turned out to be extremely easy to install, and it made a huge difference in my comfort level immediately. If I'd known it would be so easy to put on, I'd have ordered this a year ago! The quality is higher than what was originally on my violin, too - very sturdy.
