the ultra nocks are easy to install and change string position. i have been using them for like 8 years now . never had one come off or a screw come out whether im using loc-tite or not. i dont care about speed i just know they work just as good as a loop.i tried a loop last year and the only thing i found was that a loop wears out. i never had a release jaw wear out either. if anything the jaw is getting smoother with age. there are 2 different types and i have owned both. the ultra nock uses 4 screws and the true nock uses 2. its just another one of the voo-doo type products. you either love it or not. its not really good or bad to use either. i dont need a press to put my ultra nock on thats all i know.
