Worth the price an pretty good angles
Color: White, Size: without USB
So I decided to get this monitor arm because I was trying to go for an all white aesthetic and needed a arm to come in on time was a little skeptical because of the reviews but after using it, I love it. It’s super sturdy. The monitor arm is pretty high-quality. It uses mostly metal and the cable management is really good. I definitely recommend it.

Easy to use
Color: Black, Size: without USB
Easy to use and set up. The quality of the item seems to be there - sturdy enough to hold my 34” ultra wide Samsung monitor. Worth every cent with how easy it is to use and readjust the angle of the screen - I had to stiffen the resistance to account for the added weight of the monitor, but the fit and stability is spot on once the adjustment was made; just a few turns of the screw with the included Allen key

Great quality and price
Color: Black, Size: without USB
The arm needed some additional tightening, but it’s holding my 32 in monitor perfectly. Great stability and mobility. The cable organizer is a bit awkward, but works well enough. I’ll probably stick with this brand in the future; the cost vs quality is amazing.

Great stand for the price!
Size: Quad, Style: Glass Free Stand, Size: Quad, Style: Glass Free Stand
It is a great stand. I was able to put everything together myself.
Just wanted to point out a couple of things here. I have 2, 27" flat montors and 2, 37" curved monitors. Now the description says it will go up to 27", but I was able to get the 37" ones on this stand also. You can put them side by side - they will fit, but make sure you don't go over the weight limit, so for mine, to be sure I didn't exceed the weight limit, I have the bottom of them sitting on the and foot of the frame itself. You will not be able to angle them inwards toward yourself if you have 37" curved monitors. This is what I was hoping to do I just needed an extra inch on each side to move them out, for now I will just leave them side by side.
For assembly, because I was doing this by myself, I found it easiest to leave all the moveable parts loose and lay the monitors out on the floor face down in the position I wanted them in (NO CABLES). Then I took the mostly assembled frame and adjusted it to my monitors. I put the plates on the monitors and then slid the appropriate piece of the frame onto each plate, still leaving most parts slightly loose (giving myself just enough play to move things around when I stood it up). I then stood the frame up and firmed down all the fittings once I got everything where I wanted it. I then lifted the entire stand with monitors up onto my desk and then began plugging in all the cables and cords.
I really like the stand and it is a great value for the price. It is very sturdy with my setup. I just wish it had about an extra inch on at least the bottom two arms, but overall, definitely a great stand.
(sorry for the bad photo but these are my work monitors and I could not show what was on the screens)
