VIVO Quad 13 to 30 inch Monitor Free-Standing Mount, Fully Adjustable Desk Stand, Holds 4 Flat or Curved Display Screens, STAND-V004F

Oh this is joy, easy to set up with only a few wrong turns, the picture guide shows the right way to put the identical bits of pipe together to then allow you to realise its upside down but no real problems. Hung my monitors and sat back and admired my new set up....ooooh i am batman, i have to look up at the top monitors and that's not comfortable to do, it takes up space, its totally not needed for my purpose, and its awesome

Brilliant

Very good quad monitor stand. The screw on ones don't work on all desks so this is a good option. However, BOLTS ARE NEEDED. It does stay up however can lose balance with small movement. Before buying id prepare two bolts to secure it to your table. Otherwise, very good stand.

It's a good stand for the price. However, I tried to mount four 24 inch Samsung monitors. Depending how where you position the arms of the stand, the stability can reduce dramatically to the point it can tip.So I decided to drill a 10mm hole through the stand and use 10mm stainless steel bolts to bolt to my desk. Now totally secure.Just be aware of this when buying if not buying a desk clamp stand like this one

The product is perfect, and when balanced it’s very secure. Had thought to bolt it to the table but not needed. Very happy with the purchase
