I was sceptical about this one due to the lack of reviews. Further, similar items exist on some Australian websites which do not say much. I didn't want to spend $300 plus on an arm if I ended up not liking it. I was also worried that I would find it did not suit my workspace ideally, so I took a bit of gamble.
I was pleasantly surprised to see the arm seems to be of good quality. It is very stable, and installation was straightforward. I am only using a single 24" from Dell, but there is no sag or drift right now. However, the included cable management clamp and space within the arm to store cables are limited. Overall, it seems to be an excellent product for the money.
