Quality and value. Does the job great with no concerns of any failure. Excellent value.

The media could not be loaded. I’m using the MA20P-S heavy-duty monitor arm to hold my 43” Dell P4317Q Monitor (approx. 39 lbs) on a slab desk, and it handles the weight like a champ. It has cushions so you don't damage the slab table. The pneumatic height adjustment is smooth and easy to dial in, and the modular extension arms offer great flexibility for finding the perfect viewing angle. I also purchased the ULTRARM Heavy Duty Extension Arm to add to this setup allowing for the 27" monitor next to it.The build quality is excellent — all-metal construction, no wobble, and installation was straightforward with clear instructions. Just make sure your monitor has a VESA 100x100 mount. If you're running a large setup and want desk space back without compromising on stability, this is a top-tier choice.

The arm works great it's sturdy and it's so much better than the huge legs that comes with the 57 inch monitor. I gave 4 stars because the piece marked "H" in the instruction manual had a defective bolt. Both bolts are supposed to be tapered to sit in the base plate that is used to tighten to the bottom of your desk or table. One was tapered the other was not. I could have easily went to the hardware store and picked up another, but that's not the point. I didn't get what I paid for. I decided to put the customer service to the test. They were great. I had my part in a box and shipped to me the following day with tracking and 48 hours later it arrived and I installed it. I was frustrated by this oversight, but the fact that I was taken care of immediately they were very apologetic and understood that their customers expectations weren't met said a lot. Aside for having to wait a few extra days to get my gaming area set up just right, so far, I have no other gripes. In the even I ever needed something from this company again I honestly wouldn't hesitate.

Easy to assemble. Allows me to easily mount my 34 inch ultrawide in a stacked configuration over my 49 inch Odyssey G9.

This arm works great for Samsung 57. I was worried it would not hold it up, or giggle on my desk but no issues.Things I really like about it:1. The screw to adjust the angle of the monitor. I have had other arms that would let the screen tilt forward and was always a pain to get just right or if it got bumped it would face down and I would have to bend it back into position and it was always difficult. With this one there is an allen screw to adjust the forward tilt and, wow, all arms should use this method. Not only does it not dip when I touch the monitor but you can easily dial in the angle. Nice job.2. It comes with a nice allen tool and has 2 bolts to secure it to the desk. It holds really tight and appears it will hold on and would likely break my desk off before loosing grip.The quality is great.

Arm was about to break off just with mounting the monitor. Absolute pain to assemble and even worse to set up and you will scratch up your monitor in the process.Fits a 1 3/4 in desk just fine but no point if it’s just going to tilt over. I tightened the lower bolts more than enough and it would barely hold its own weight.If you’re getting this to mount a 1600 dollar monitor you can spare the extra few bucks to get a mounting arm that will actually work.
