ULTRARM Heavy Duty Extension Arm [Accessory Only - Requires MA20P-S Single Monitor Arm for Use] Dual 49" Vertical Stacked Monitor Mount Height Adjustable - 100x100 VESA Mount, Black, MA20P-A

Very happy. Bought another after I made sure it met my expectations. Very nice product and easy to use. Could be maybe a bit more buttery smooth in terms of minor adjustments but for the price it’s amazing.

This is the first monitor arm I bought and i dont usually write reviews. It maybe pricey but its actually worth it. Feels very heavy duty. Would recommend this. Came with necessary tools as well

Really good monitor arm - has a smooth adjustment mechanism and easy to install. I bought this arm and an extension for a seconds monitor. It does a great job handling my two 32” monitors.

Great quality. Very strong. Holds my Samsung Odyssey 49” like nothing.

AWFUL.First, it is definitely not easy to build and install, all the comments saying so are deceiving. It was so complex that i first asked a relative for help building it, and then even he had difficulties, so i took it to a computer and technology equipment specialist store and even they said it was too complex.Second, it is incredibly heavy, toooooooo heavy, if you want your desk to break, then go ahead and buy it. Honestly, i would never recommend this risk. My desk is even made up of thick wood and this is too heavy for it.My advice, stick to your normal monitor stand and dont go for complex and expensive stands like these because it is not worth your money or your desk breaking.Also double check compatibility of your monitor before buying.

I used many Stands, but it’s like Makers know what we exactly need. Highly recommended.
