I bought one of these last year for work and it has been great. I have a sit/stand desk at the office and this arm has been rock solid. I adjust it up when standing and down when seated. It worked so well that when I wanted a new monitor for my home office, I didn't even look at other brands and just bought another one of these.It works as expected, is stable and easy to adjust the tension to get it how you want. Great product, super easy to use, great quality materials, and works a treat.my ONLY complaint that kept this from being a 5 star rating is that there isn't any detent or index in the rotation head that sets you at level. As you can imagine if you are moving up and down often you may rotate it slightly. It would be great if there was some kind of 'notch' when it is level so that you aren't staring at your monitor trying to make sure it is level after you've moved it.
