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.

Excellent stand
Size: Dual, Style: Glass Free Stand
I love the functionality of this stand! It is very durable and stable. It does not require any form of anchoring to hold monitors. I have two 27 inch monitors attached to my stand with no problems. The stand can be moved in various direction with little effort. Excellent stand if you are looking to enhance your office space.
