Product thoughtful, finish is reminiscent of a solid product that will take time. Contrary to the comments I have read on this article, I did not notice any game in the mechanics of this support. An adjusting screw can "paste" the arm supporting the drill to the rack. The thumbscrews enable rapid assembly / disassembly drills without tools. Ditto for the height adjustment, all done without tools. Done his job perfectly. One star less because despite the clip to secure the cable to the drill, the latter often takes in the handles which are used to lower the support. The support may also be mounted 180 °.
