    Worth the money!
    Size: 50mm/2inch, Color: Black, Number of Items: 2
    This kit is great. I bought this because I know that the seller paired the cutting tool to be the perfect size and it was! Not just that, but the hole cutter was well done and cut thru the 3 layers - laminate, plywood and particle board with ease. The only thing that I would do different, is go to 3" next time. 2" was very tight when running the 2 @ 120 volt cord ends through the cap.

    Very sturdy under desk mount
    Color: Black, Size: Width up to 13.4''
    I'm using this with an Asus Prime micro-ATX case on a sit/stand desk, and it works beautifully. It's expandable, so it would have no trouble with a full ATX case. The PC is well supported and there is no wobble whatsoever even when the desk is moving between sitting and standing positions. Highly recommended.

    Amazing mounts my gaming rig under my desk so that I can move it up and down without worrying about cables and such also makes the cable management a lot easier.

    Great computer mount but was missing some parts
    Color: Black, Size: Width up to 13.4''
    Works great but was short 1 machine screw, and had no wood screw for attachment to the desk. The brackets them self are great.
