  • The Best Monitor Arm I’ve Ever Used
Color: Matte Black
So let me start by saying that this is the absolute best monitor arm I’ve ever used. The stability, the strength, and how universal the construction of it all is, it’s actually astounding. The maximum size and weight each arm is rated for is 27in and 20lbs, but the curved 32in MSI Optix I have on a single arm is at least 20lbs. I haven’t modified the strength or locks on either of the arms or mounts, and they feel rock solid. Ergotron actually thought of everything. My desk, like many others, has a ‘lip’ or edge that hangs off to increase the structural integrity of the desktop. This started to worry me as I wasn’t sure if the clamp-press mechanism would be wide enough for the edge ‘lip’ hanging from my desk. When it arrived it was exactly that size fully widened, so it wouldn’t fit. However in the box there were parts to convert the base of the arm to attach to a desk via a bolt through a hole(e.g. a wire organizer hole, drill hole). This saved me from having to heavily modify my desk or return the arm, and made the entire building process a breeze even with hurdles in the way. ... show more

  • Excellent (but expensive) monitor mount.
Color: White
This is an excellent monitor mount. I now have two of the dual mounts, one at work and one at home. Easy to assemble, very stable, and with good movement and positioning. I've also used their single-arm mounts and can recommend them too.

  • You get what you pay for, and these are worth every penny
Color: Matte Black
After trying many desk mounts of different styles, these by far have been the best. Pricey, but worth it in the end because there is ZERO wobble. My desk wobbles more than these do, they stay planted.

  • Best there is, room for improvement
Color: Matte Black
Arms are very solid construction and few corners were cut. I appreciate the simplistic zip tie solution for cable management, but do wish for a clamp instead of just letting the ties hang. The arms are sturdy and I am still dialling their tensions as I use them. I move my monitors frequently for different applications and so often find myself needing to take care when raising the height to avoid popping the caps off the second arm base. I would have appreciated a bolt on top of the arm connections to prevent them shimmying up when moving my monitors up. Overall very good. Probably the best there is for now based on my research before purchasing. ... show more

  • Expensive, but worth it
Color: Matte Black
I've had several other brands of monitor arms, and this one is by far the best. It's expensive by comparison to some of the other brands available but the range of motion and stability cannot be beat. Assembly is pretty straight forward and uncomplicated, I docked one star only because the wire management is just a little snug which makes the covers difficult to pop on/in place. The mount installed easily onto my versadesk stand up riser and makes adjusting my screens quick and easy. I can spin a monitor to face my guest chairs while keeping one facing me which makes collaborating in my office easier. The monitors stay in place until you want to move them, and when you want to move them it takes 2 hands but not a lot of force. ... show more

  • Love Them!
Color: White
I have a Dell 34” wide screen curved monitor and Dell 28” monitor on these and they work perfectly! They have a wide range of movement so you can tilt the monitors and access the bottom/back to manage cords and whatnot. Sturdy and well built with great resistance which helps keep the monitors in place. I highly recommend these!!! ... show more

  • Viewing angles limited. Bad clamp design and options
Color: Matte Black
This arm is a catastrophe. The viewing angle is angled up towards the ceiling and for some reason, unchangeable. There was no engineering here just a cheap copy of the item I should’ve purchased (would love to know what it is). Very disappointing

  • Well designed and heavy duty monitor arms
Color: Matte Black
Wow, these are fantastic monitor arms. Very heavy duty and well designed, the arms were easy to setup and position. The manufacturing for these arms is flawless; really well done using quality materials. I thought that some of the design features are very well done. Good resistance to movement, nice cable management channels, tool-less VESA mount screws. I'm really enjoying these arms and will be selling my other aluminum arms shortly. I purchased these because of Ergotron's prevalence in hospitals, but am now an Ergotron fan because of my stellar experience with their product. I've got a second set of monitors that I need to mount and will be purchasing a second set of these bad boys. ... show more
