How to put this gently...? These screws suck. I've got 4 of these. Every one of them is about twice as hard to place as my BD Express or Turbo screws. Maybe three times as hard. Very hard to start; I've been stuck leaning on one of these things, cranking, twisting, really pushing, and it just spins in the half-inch hole its made, and doesn't bite any more. Spins and spins and doesn't bite. Once they do bite and start going in, they are almost always so hard to turn that I can't just hold the rotating hanger and crank; I have to grab-turn-release, grab-turn-release, again and again until it's in. By contrast, with every one of my BD Express screws, once it has started to bite and it's in about an inch or so, I can just grab that knob and spin away and moments later I'm climbing again. With my one Turbo screw I use for V-threads, it goes in just as easy, sans knob. The Laser Sonic is simply an inferior screw. The threads are dull and have all kinds of manufacturing artifacts all over them (in the picture note the notch on the thread on the left screw and the textured band on the right screw). These really suck. Really.
