All of these products have a "Pole/Grommet Base", rather than a clamp or stand style desk-mounting design. Grommet mounts are not very well known but are in fact the best of both the stand and clamp mounts put into one base. Also known as pole mounting brackets, these are a great option for anybody. They fit firmly into the holes on your desk (meant for wires), and clamp onto the bottom securely. They have no overhang (like the clamps do), and they take up much less room than the stands!
