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.

nice stand, quick easy setup
Size: Quad, Style: Glass Free Stand
nice stand, easy setup, I like that you mount the bracket to the monitor first and then hook it onto the stand. This makes for a quick and easy setup. You do have to wrench down on the screws to keep the monitors from moving. Also you may want to have 4 of the exact same monitors so they all are at same height. I have two that are the same and two others that are different so they dont all mount at same level. I plan on ordering monitors to match.
