  • Heavy duty, works GREAT, makes monitor easily repositionable ....
Color: Polished Aluminum Size: 13 Inch Pole
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 ... show more

  • A very excellent mount for a monitor
Color: Polished Aluminum Size: 13 Inch Pole
This is a very excellent mount for a monitor. It is beautifully designed and made. It is quite heavy & sturdy. The design is superb. The parts are all made of heavy duty steel and bolted together with fine screws. There are 2 Allen wrenches for adjustments. I used the through table mount but there is also a C-clamp mount. It can be used with 1 or 2 arms depending on your needs and size of the space. I used 1 arm. The instructions that came with it were detailed and excellent. I had no trouble assembling and installing it. There are also on-line instructions and several videos at the website of the manufacturer. It is fairly expensive for a mounting, but it is a pleasure to have and use. I expect it will last a lifetime. As the instructions note, it is difficult or impossible to move it well until the VESA plate is screwed onto the monitor. After that, it is readily moved. The Allen screws and be adjusted to more or less tightness. ... show more

  • Great choice--great value
Color: Polished Aluminum Size: 13 Inch Pole
5 stars, not because there are not better ones above this price range(e.g., Humanscale at $240plus) but because nothing seems to come cloese naywhere near or belwo this price range. The cheaper ones are no more than clugs with badly fitting parts and whose screws need to be loosened, if they haven't been stripped, if you want to move the monitor position. In its price range and above I haven't yet found a decent competitor except for the Humanscale M2 or M8. The LX is a well made, nicely designed, unit well worth the price. At first, it wouldn't hold my monitor up -- the upper arm kept sinking -- and yet my monitor, at 15.4 lbs., was well below the 20 lb. max capacity for this unit. The adjustment for the weight of the monitor is #2 on the scant pictographic instructions. The picture instructions are not the best--not the worst but. . . Anyway I searched for an adjustment to the spring-tension canister in the upper arm that counterbalances the monitor's weight. Pushing the upper arm up and the screen mount down reveals the adjustment screw head at the end of the canister and the larger supplied wrench fits it. 3 half-turns clockwise made no diff. So I added three more half-turns; better but still slowly sinking. I added a 3 more half-turns--much better. 3 more for a total of 12 half-turns and the balance was perfect. You need to ease your way up to the right number of turns to get it just right balance and to avoid overtightening. Once adjusted correctly, the montoro stays in palce but can be moved easily up and down. What's nice about this unit is that, once you have it set up, you can move the monitor around and up and down without readjusting the tension or loosening/retigthening any screws. Although, if your desk is on casters or wheels, you will want to lock them, which is a good safety rule anyway. The elevation movement is smooth and easy--you can move it up or down with one finger. The horizontal swing movement is much stiffer. It helps if you spray the two large post joints with silicone lubricant liberally and then wipe away thoroughly all of the excess. This won't make the swing movement light, but it does ease it up a bit. By post joints I mean the large joints where the upper arm meets the lower and were the lower arm meets the desk mounting post. These joints have no bearings; they have plastic sleeve-type bushings. Compared to the Humanscale: the Humanscale moves horizontally as easily as the LX moves vertically while the Humanscale moves vertically as stiffly as the LX moves horizonstally--either way I'm not sure the difference is worth the extra money for the Humanscale. This stiff horizontal movement is less than ideal but far better than what I've seen on some of the cheaper units offer. For this price I could live with stiffness given all the other postive features. The LX comes with a heavy duty clamp base and a drill-a-hole-in-the-desk grommet type mount--both come in the box. All of the parts are in a two-layer plastic strip, sealed into multiple compartments with each compartment labeled as to contents. Much better than those units that come with all the screws etc. all in one bag and you have to sort them by count and looks against their picture in the instructions. It's not quite as pretty as the Humanscale M2 or M8, which cost about 60% more, but much more nicely finished than the cheaper units I've seen up close. The LX, with less attractive desk mounting pole, has a greater range of vertical position than the Humanscale. If you can afford it, this monitor arm is a very good choice. If you can afford more, then it's a tough choice between this at its price vs the Humanscale arms at the higher prices. For the money, this is a much better deal, thus, my rating of 5 stars. ... show more
