Excellently product for the price, very sturdy and well built, the grip can loosen over time so be sure to tighten from week to week, but once I get it really tight it'll stay that way for awhile, make sure it's a thick desk as I believe it needs to be at least an inch and a half, i jerry rigged mine by cutting a block of wood to make up for my desk being too small, make sure your desk also has a couple of inches between the vertically downward lip
