BUYER BEWARE!! ITS GARBAGE YOU WOULD BE BETTER BUYING A $20 MONITOR MOUNT INSTEAD
Color: Black, Size: without USB, Color: Black, Size: without USB
This is the second review I ever gave on Amazon out of thousands of items I bought over the years.. This is the worst monitor mount I ever bought I have purchased maybe ten over a long period of time this monitor mount isn't the cheapest so you would think your getting quality your not it's garbage worse than garbage because it can break your monitor mine decided to give out and slam down thankfully it didn't break my $1100 oled monitor also it has weird screws you have to screw in to get it to rotate 360 degrees it has a screw that clamps down on your desk and will leave a mark and damage it.. To lower it you have to turn it 500 times loosen it up and it never feels stable also the tilt feature is litterally the worst no matter how high you try to level your monitor it always hangs downwards I have a light monitor well within the weight capacity.. I would buy any other monitor mount so buyer beware if you want junk and waste your time fiddling and trying to get this in a good position you won't and it will just get you super aggravated I wish I could give this item zero stars

Worth the price an pretty good angles
Color: White, Size: without USB
So I decided to get this monitor arm because I was trying to go for an all white aesthetic and needed a arm to come in on time was a little skeptical because of the reviews but after using it, I love it. It’s super sturdy. The monitor arm is pretty high-quality. It uses mostly metal and the cable management is really good. I definitely recommend it.

Otherwise it is great

Easy to use
Color: Black, Size: without USB
Easy to use and set up. The quality of the item seems to be there - sturdy enough to hold my 34” ultra wide Samsung monitor. Worth every cent with how easy it is to use and readjust the angle of the screen - I had to stiffen the resistance to account for the added weight of the monitor, but the fit and stability is spot on once the adjustment was made; just a few turns of the screw with the included Allen key

Great quality and price
Color: Black, Size: without USB
The arm needed some additional tightening, but it’s holding my 32 in monitor perfectly. Great stability and mobility. The cable organizer is a bit awkward, but works well enough. I’ll probably stick with this brand in the future; the cost vs quality is amazing.
