It is so hard to align and to get the monitors side by side without gaps. I got it, I thought, and then accidentally touched it and it got loose and the screens are now swinging around. Been turning the screws and still won't tighten and stay put. Wish I got something else.
The quad monitor stand does a great job at allowing you to move the monitors how you want. Articulating the arms and head pivot piece allows you to move the monitors from side to side, front to back, and adjust the tilt. Moving up and down requires you to manually move both the connection to the main support, as well as the limiting bracket on the main support. Both of those require tools (provided with the stand), but are very simple to do and I was able to get my monitors in position in 30-45 minutes from opening the package. Once the stand is set up with monitors, it is very stable. I did some tests, and the only time the stand struggled was when I pushed all monitors to one side (which is not realistic at all since you end up blocking 2 of the monitors by doing this). In every other realistic (and most non realistic) scenarios, the stand was rock solid.
Product came with tattered box and scratch on the poles but seller was very responsive and happily sent new replacement parts. Other than that, the stand is very stable and firm but flexible enough to be able to adjust the arms. Very happy with it so far.Edit: Decided to crank up the monitors on it and found the arms were too weak to support 2 27 inches monitors on the same level which both were way below the maximum weight supported. Returned the product and was refunded on time. The support team also provided constant communication so I did not take off a star for that.
If you are into stocks and have multiple monitors, this is a must if you want desk space so you can actually have a place to do you work. Must have!
This is as good as the version I paid over $300 for. I think they are even the same brand.
