"[The] gizmo I can't speak more highly about is the EZ-Mount cartridge screw set. Delivered in a set of four pairs, they have an easy to tighten knurled knob on top eliminating the need for tiny hand tools. ...you can use them to add or remove mass to the headshell... All you need are your hands to install the EZ-Mounts, particularly on pre-threaded cartridge bodies, and they make cartridge alignment easy since they're a breeze to untighten, move, and retighten. Genius."

 "Why Didn't I Think of That? While this set is particularly useful for reviewers who are constantly changing cartridges, it should also prove useful to audiophiles who don't enjoy fumbling with Allen keys or tiny screwdrivers."
- Michael Fremer, Stereophile Magazine, December 2010, Vol. 33, No. 12, Page 39
