[1] Many table-top desks have unlimited clearance underneath and there for any old mount would suffice. Unfortunately, my new desk has a back panel with a hole leaving only 2.5" of clearance. I didn't plan things well, so I needed to chuck my old mount and find a specific mount to fit this desk.This mount has great form factor in the mount/base. My desk is exactly 2 inches thick with 2.5" max. clearance on the bottom side. The clamp mount fits perfectly and securely with room the spare. The bottom lip of the clamp is about 1/4" thick and would probably fit almost any narrow space.The top lip of the clamp -- visible above the desk -- doesn't look half bad either. It looks like it belongs there. It also has padded feet so as to minimize/eliminate any damage to the desk surface.After mounting everything, I noticed my monitors needed to be centered differently. All it took was a few turns of the bolt/screw to loosen the entire base and then I could slide it sideways, position, and retighten it. I appreciate the fact that I didn't need to juggle anything (or climb under the desk) in order to reposition everything.[2] My old mount was a single unit, which made it unwieldily and risky to install by myself. I could never figure out how to attach the monitors after mounting the rig, so I'd always end up lifting and attaching everything -- mount, arms, and monitors -- as a single giant unit. Ever broken a sweat while setting up your monitors?Their claim of "5 minute installation" isn't really an exaggeration, though I'd say more like 10 minutes if you count the cable management. For each arm of this mount there are 3 separate, well-designed and well-fitting pieces.: the VESA plate which attaches to the monitor, the top part of each arm, and the bottom part of the arm which attaches to the mount.I really appreciate the fact that the VESA plate is a separate "quick release" unit, which means I can simply snap my monitor on and off the arm, as needed.[3] The form-factor of the arms is great. It looks and feels high-end. I have two 27" curved monitors and was able to get the full, side-by-side, curved layout that I'm accustomed to.My only complaint -- if you can even call it that -- is that in order to position my monitors lower to the desk, the arms would need to extend 3-6 inches behind the desk, requiring the extra clearance to do that. I can't really fault the mount for that though, as I don't see how else it would work.[4] The arms also included nifty cable management. Each arm has a detachable back plate where you can run your display and power cables. The fitting is tight, so it could be a problem if your cables are extra thick. I was able to make it work, though it was a tiny bit frustrating. The end result looks amazing though -- cables completely out of view.[5] Overall, I'm extremely pleased with this purchase. Almost every other model with the same style of arms does not have the same style of base/mount, so I'm more than willing to pay the extra $20-30 to get the perfect mount for my desk and monitors.
