I bought this arm to replace a much cheaper version sold here on Amazon for about $100 less. It just wasn't made quite that well, and did not have the positioning abilities that I wanted, plus it wasn't tall enough for my standing desk. This arm is much, much better - it's very well made and holds my monitor very securely. It's also very easy to move the monitor to just about any position I want with very little effort. So it works for my stand up/sit down workstation, which is just what I needed. Why four stars? Because I am 5'2" tall and this are does not have the height I was looking for. Unless there's an adjustment that I don't know about, maybe. From what I've seen, it looks like the top arm is at its highest position just like in the picture on Amazon. I can get the monitor to go down, but no further up. It's impossible to tell from the very scanty instructions which joints are repositionable and which aren't, so maybe I just don't know how to get it to go higher. And I also may be too picky, but I want my monitor at eye height so I don't have to look down at all, I want to be able to look straight ahead and have my information straight in front of me. This arm is about 3" too short of that. So I have the extension arm on order, and am hoping that will give me the extra couple of inches I want for this arm to be perfect for me. However, this is just a personal preference. Other than that, this is a great piece of equipment, it looks like it's built to last forever!!!! Easy to install, too, even with the crappy instructions. I would recommend this to anyone who needs to be able to reposition a computer monitor regularly, especially if you're in a stand up/sit down workstation like I am. This arm is just perfect for that, with the exception of the height problem. And that may not be a problem for anyone else. If anyone out there knows how to adjust that top arm to go higher than the approximately 45 degree angle it's at please let me know! Overall, very well worth the money and I'm glad I shelled out the extra bucks to move up to this arm from the one I had.Update: I received the extension piece for this monitor arm that is sold here on Amazon. It's basically the same piece as the part that attaches to the pole. It took all of a minute to install and re-position my wiring, and the height problem was solved! Now my monitor is at eye height, which is exactly what I was trying to get accomplished. So now this is a five star review! If you're interested in the extension arm, it's the Ergotron 45-289-026 Mounting Extension. It's a bit pricey for what you get, but it solved my very irritating problem, so it was well worth the money. My workstation is now set up exactly the way I want it, with no eye, neck, or back strain from bending over just a little to get closer to my monitor screen. This is an excellent, heavy duty product and I can see no reason why it should ever need replacement. Here's the link: Ergotron 45-289-026 Mounting Extension

The Ergotron LX is one of the best monitor arms you can buy on the market.They are an industry brand that sell to businesses so they are reliable. Sure you can buy a way cheaper monitor arm, but this one will retain its tension, doesn’t make any noise while moving it, has great location control, and looks amazing.The installation is easy, and the amount of space it takes up is minimal.I’ve had mine for months now (this is a late review after trying it out for a long time) and I love it. It included everything necessary for installation.I am using it on a 24 inch and 27 inch monitor and it works flawlessly. It holds them well.I would say if you have the money then buy this for sure. Don’t buy a cheaper monitor arm if you can afford to buy this. It’s worth the money.

This mount is perfect for what I bought it for - having a lot of versatile movement of my monitor, so that it can be adjusted frequently. This mount is not a set-and-leave type, where you need to set it once and stick with that location. You can adjust it as much as you want, and it holds position. The only adjustment that may take some time to make is the position of the arm on the pole, because a ring underneath the arm must be adjusted to maintain the height position. However, the height range without adjusting the arm is already pretty significant, and I do not see that it would be necessary to adjust the arm height on the pole very often. Adjustments are smooth and they stick - I do not have problems with the monitor falling out of position after I adjust it.The other reason that I picked this particular unit (besides the ability to adjust frequently and easily) is the tall pole. This provides a larger range of movement, and if your monitor is on the upper end of the rated size scale, you will probably need it. I was really happy about this choice, and although I have not really needed that extra height yet, I am really happy that I have the potential for it.When the mount arrived in the box, my first impression was that the parts were all solid and well-made, heavy construction. Assembly was really easy (no-brainer) and when put together, it was clear that the quality construction was as solid as I thought, and all parts worked smoothly together and fit easily. Ergotron did not stinge on any of the parts - they are all solid, good quality.I mounted it to the desk with the clamp, instead of drilling holes, because the desk will be moved to a new apartment soon, and I want to have flexibility of placement in the new place. The clamp provided good stability for my monitor, and I have had no problems with vibrations or the clamp slipping while I am adjusting. I may leave it in the clamp even after moving, since I have not had any problems with it.I was torn about purchasing the dual mount so that I could have the flexibility of setting up dual monitors in the future, but ultimately decided not to. Now that I have the mount, I realize that I can buy the same mount again and mount both arms on a single pole to achieve the same setup as the dual mount system. Or I can set the mounts side by side. So, I feel I made the right choice and I am not limited.Overall summary: highly recommend!Pros: quality parts, solid construction, easy assembly, easy adjustment, adjustments hold after you make them, extra height range with tall pole, choice between clamp or through-desk mounting, rotates freely between portrait and landscape viewing (fun fact - this rotational direction is not limited at all except by your cables that will wind up if you continue to rotate - you could keep rotating indefinitely if your monitor were cordless).Cons: takes a little more time to adjust the height position of the arm on the pole (this is no big deal for me). Also, having a wall directly behind the mount will limit movement away from you to some degree, because the arm will be restricted by the wall - you will not be able to retract it as far against the wall as you would if the desk were free-standing. However, it seems obvious that you will not be able to achieve the full range of movement if there are obstructions.
