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)

Perfect! Level monitors, small footprint!
Size: Dual, Style: Glass Free Stand, Size: Dual, Style: Glass Free Stand
Perfect!
This was the 3rd monitor stand I purchased this month. The others either were too bulky of a base and/or I could never get the monitors level! This is perfect! Was easy to assemble and it’s easy to move them & adjust tilt & spacing.

Sturdy with good finish
Size: Dual, Style: Glass Free Stand
Easy to set up. Good finish. Sturdy.
Using 2 x 27" monitors .
A bit difficult to align them seamlessly. Suggest getting monitor alignment aids together with this.

The best Quad Monitor Mount under $100
Size: Quad, Style: Glass Free Stand
Great monitor stand. I got the Quad. It's base is nice and you can put stuff on it unlike the other popular quad mount that is V shaped. You can get the monitors 98% aligned, then use gaffers tape for the last 1% (99% perfect, slight gaps that I couldn't fill). Strong, sturdy, tempered glass base, metal pole. And cheap price. This is the one to get for a quad setup. I stripped the bolt on the VESA monitor mount bracket and the seller took care of me. No worries.
