This monitor arm mount clamps securely onto my desk and my monitor stays right where I put it. All the adjustments make it easy to get the monitor right where you want it and you can lock it down so it stays put or leave it looser so you can reposition it often.
It mounts to any monitor with the standard VESA 100 or 75 layouts and comes with shorter screws for flush mount and longer screws with spacers for monitors with recessed mounts. There is a desk clamp mount which will fit on some fairly thick desks as well as a keyhole type mount if there is a hole in the desk already.
The black and silver finish looks good. I’m very happy with this monitor stand.

Full Disclosure: I received it for free in exchange for my honest review.
