HUANUO Heavy Duty Monitor Arm for Ultrawide Screens up to 49", Holds 40 lbs, Ultrawide Screen Desk Mount,Fully Adjustable Single gaming Monitor Stand with C-clamp, Grommet Base, VESA 75/100

This really is excellent. I bought a lesser product prior and it simply couldn't hold my ultrawide monitor upright, but this Huanuo manages it easily. It's very well made and the finish is of a high quality. Easy and quick to assemble/install. All necessary tools and screws provided. Instructions are illustrative and easy to follow. Packaging is excellent and prevents parts from sustaining damage in transit. Not the cheapest, but the volume of sales and positive reviews should tell you what a good product this is. Robust feel and dampens any vibrations well.

I was sceptical about sticking a 49" monitor on this arm but its is solid and very sturdy. The monitor is stable, the adjustments are easy and it does what it says. Very happy.

Really solid. Held my 25" touchscreens with ease and facilitated the 90° rotation I needed. They need about one inch between desk and wall and are quite easy to attach with the dual clamps. They arrived very well packed.

I've got there smaller one that hold less weight for my 27inch Montior and its fully made out of metal, This one at double the cost and rated to hold alot more weight but it is made out of plastic and metal, however, at the connecting arms where it takes the most amount of stress, it's made out of plastic on the female side, same with the base as well on the female side. I like the method off tilting it forward and backwards. It's on a ratchet system so you pull up and then you ease it down to your preferred level The spring tensioning in the arm itself allows you to freely and easily move the monitor up and down wherever you need it, It doesn't sit as flat to the wall as a lot of other stands do and when you pull it out or up and down the assembly wobbles quite a bit. Only time will tell if it lasts or not.

Super sturdy, but sits far too far away from the wall for my install - much further out than my previous mounting arm. I returned it.

it seems very sturdy and the build quality is really good for the price.
