I bought a Kreddle at the suggestion of my teacher and it does help you to stabilize your violin if you have a long neck or need other adjustments. I am still messing around with mine, but do find it already more comfortable than my original chinrest. I think the Kreddle is made from a hard plastic, which makes it less attractive than my original ebony chinrest. For you people with nickle allergies, you can buy one with stainless steel posts and that was a godsend for me! If you use a paperclip as a chinrest wrench, make sure not to push it all the way to the wooden side of the violin and scratch your varnish! I got on You Tube and watched a few videos on how to change out a chinrest before I took the plunge and do not regret the extra time I took.
