Ergotron LX Single Monitor Arm - VESA Wall Mount Bracket for 13-34 Inch Screens (7-25 lbs) - Adjustable Aluminum Stand for Home Office & Gaming Setup

This is a seriously nice product. There are few wall-mount swing arms that offer the versatility of the Ergotron Lx. And there are even fewer that compete at this price, which is substantial but worth it in my opinion.Right out of the box, you can tell that this is a quality product. From the heavy 80mm hardened steel mounting bolts, to the mounting wall anchor with plastic vanity covers for the bolts, to the precision movement in the arm itself, there is no doubt that you are getting what you pay for. The Ergotron Lx both looks nice and feels nice. I am very happy with my purchase, which was hard to do. After all, it's ~$120 just to mount a monitor on a wall. But when you consider the quality of the product with the ergonomic configurations it offers, it's totally worth the cost. And let's be honest, ergonomics are expensive in general, so this is really not such a terrible price.The product installed relatively smoothly. I did not have a drill bit that could completely bore an 80mm hole to accommodate the massive bolts, but after some ratcheting it all worked out. After that, attaching the VESA mount to the Monitor was a cinch with included thumb screws or, if you don't like thumb screws, Phillips-head screws. But who doesn't like thumb screws? Then it was just a matter of sliding the arms on top of their respective mounts. Adjustments for each of the joints could be easily done with an Allen wrench (provided, if you don't have one).Adjusting the Lx was simple enough. You can tighten the spring-arm so that it can support your monitor weight or you can make the joints stiffer or looser per your preference. I found that the joint to swivel the monitor right and left was a bit stiff even at its loosest, but I don't take issue. The adjustment to tighten the spring-arm is hidden so you'll need to read the manual to find that one.The manual was quite detailed in many respects, but could probably benefit from some proof-reading. There are no explanations -- only diagrams. And not all of the items pictured in the diagrams are accurate. Minor stuff though. They'll have a picture of a Phillips-head screw, but be using a hex Allen wrench in the diagram. The manual is also laid out weird so that it's not completely obvious which diagram is relevant. But the product is fairly simple to install so the shoddy manual is forgivable. I found that the suggestion for a 3/16 drill bit to bore the hole for the 80mm bolts was insufficient. I went a little larger myself.Among that which has already been described, the unit also includes a plastic cover underneath the rear "bone" of the arm to manage cables to your monitor. It clips in nicely to neatly hold strong a decent amount of cable. The arm itself has a very impressive range of motion. When you move it up and down, it moves the VESA mount synchronously to maintain the configured angle of the monitor.The reason I purchased this was because my monitor was too far across my desk and I had to lean over to see causing some major issues with my mouse arm being bent and all. Now I have both newly freed desk space as well as much less pain in my mouse arm. Plus I can see the monitor a lot better. I could have purchased a $40 swing arm to get the job done, but the versatility in being able to raise and lower the monitor on-demand is quite worth it. I highly recommend this product.Positives:- Quality Design- Versatility- Ease of use and installation- Ergonomically pleasing- Aesthetic detailNegatives:- Instruction manual needs work- Only supports up to 20 lbs or 22" monitors
