This thing just works. You can even adjust the tension of each joint, with the included hex-wrenches. I found that my Samsung Note was a wee bit too heavy, for the factory tension, but I was easily able to tighten up the joints to hold it in place.My only nit-to-pick, is that the ball joint (at the center of the arms) has no provision for tightening it, after it wears a bit. My solution, was to cut fine slots between each of the 4 \jaws\" with a vibrating tool
