Pros: It holds all of my monitors well. It does the job but you really need to take caution on the Size & weight of your monitors. They might be too heavy for these arms.

Cons: The movable joints could be better designed. The tightening mechanisms could also better deigned. Some of the bolts on this are made from cheap steel and somehow stripped the bolt on one of the elbows.

Other Thoughts: I was disappointed in this product. When I opened the package I was hopeful that the strong appearance of the arm & post were of good quality. Unfortunately this was not the case. The movement and tension of this device are not great.

Pros: Quite sturdy

Cons: Was not able to 'tune' it to the weight of the monitor to go up or down and keep it there. Manual (one page) is worthless. There is a screw in a screw which I think should tune it. Contacted manufacturer twice, no response!
By now beyond the RMA window, ended up using it as a fixed stand,
