Ergotron LX Series LX Dual Stacking Arm Tall Pole 101.6 cm (40') Clamp Aluminium

Excellent so far. Will update in 12 months.

I used to have a cheap 100 dollar one. But once i upgraded to this beast. It just beat it every way. It's so sturdy and strong. Comes with thumb screw for the monitor mounts that work way better than expected and the cable management was a lot better than expected. It took me a minute because I wanted it perfect but it was super easy to put together. Just the quality of life improvement for sure. It gives my two 27 in monitors so much space to breath if needed.

This arm is rock solid, even w/o completely adjust the arms on the collars that support them, it's very sturdy. Also, I don't know why but the flexibility, to save space at the back of the desk is huge.

After reading a lot of different reviews and doing research, I settled on shelling out the cash to buy this mount. It was far more expensive than the other two mounts I had previous tried for my dual monitor setup. The previous ones were rated 4.5 stars respectively and ranged from $50 to $90.At nearly triple (or more) the price of the previous mounts, the quality didn't disappoint. The sturdiness of this mount feels rock solid and the only motion as I grab the pole and shake it is the motion of the desk I have it mounted on.It was incredibly easy to assemble and the instructions were very straightforward. I wish that, for the price, Ergotron would've added some quick releases to the VESA mounts on the monitor. Range of motion isn't quite as good as I had hoped (vertically once the arm is secured on the pole) but any desired placement of the monitor can be achieved through a combination of the arm's range of motion AND adjustment of the height of the arm where it mounts on the pole.One of the reasons I ended up with the Ergotron tall pole mount was that should I ever want to go to a 3 or 4 monitor setup, I could do so on this single tall pole. Or if I wanted to have 1 monitor above the other, that could be easily achieved as well.I would definitely shell out the extra $$ and buy this mount again. The sturdiness of it is unmatched compared to other mounts.

One of the most satisfying purchases I've ever made for an office. Monitors mount easily, move smoothly, stay where they are put, and the whole thing looks slick as heck.I have the taller version. I put two 27 inch monitors on it and mounted my webcam to the top of the central pillar. it is AWESOME.Pricey? Yup. Worth it? Double yup.
