I own 3 of these. I’ve tried ~10 other monitor arms and none have been even close to as good as this one!There are plenty of reviews on here, so I won’t cover everything. But here are the basics:1. They’re strong. Holds my 43″ monitor right where I want it. Has done so for ~2 years now. It’s ~26lbs. Another holds a 27″ monitor a Nikon DSLR just fine.2. They’re really flexible. I have all 3 clamped onto the back of my desk and they hold two side monitors at a good angle flanking either side of my 43″ monitor.3. They have a good long reach.4. They go up higher than most monitor arms. This is important for me so I can keep the bottom of my 43″ monitor ~10″ off of my desk as well as a portrait 27″ monitor ~8″ off of my desk.5. Gotta be careful with the little hex screws you use to tighten things. Gotta do it both tightly but not too tightly that you strip things. I had one strip and 3M sent me a replacement. Haven’t had any other issues – could’ve just been a bad one, even.6. The clamps on the desk are pretty large. These could handle some pretty thick desks. My desk isn’t too thick, but this was super important for me. Why? Well, I have a standing desk and I needed to build a shelf under the bottom of my desk. I didn’t want to start drilling into the desktop surface (since it’s so thin – only ~1″ thick), so I wanted another option. Turns out, these clamps are sized perfectly to allow a 2×2 board (~1.75″ x 1.75″ in measurements) to slide right in the gap between the long threaded screw and the back plate of the clamp. Since I have 3 going across the back of my desk, I just threaded a 2×2 through there and that gave me a perfect place to hang a custom-built shelf from. Some 1x2s for ridges to keep things from sliding off, a 1×6 for the bottom of the shelf, and some really long bolts to hang from the 2×2, and I’ve got me a great shelf there for small things like an audio mixer, power strips, cable management, and more!These mounts are a bit pricy, but they’re really not too bad for the amount of weight they can support. It’s hard to find a good mount that supports 30lbs that doesn’t cost quite a bit more than this one does, so I can’t complain. It’s definitely worth it, in my opinion.
