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.

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.

Fantastic upgrade from my original stand. Base is a little bulky, but stand is versatile and sturdy.
Size: Single, Style: Free-Standing, Size: Single, Style: Free-Standing
Amazing value for this stand. I needed a stand with more degrees of freedom than the original one that came with my monitor, and this stand (which was inexpensive relative to the cost of the monitor) was a great purchase. The base of the stand is a little bulky/high, and the soft material on the bottom of it can rub off very easily if you let the stand catch the back edge of your desk. Otherwise though, the stand is extremely easy to install, and it provides far more degrees of freedom for rotation and translation than the original stand for my monitor. Now my monitor is sitting at a comfortable viewing angle closer to my desk tilted slightly upwards toward me. Just keep in mind that you have to tighten down the height and tilt adjustments (the things that would be affected by gravity). So, if you want to adjust those frequently, this stand might not be a great fit for you. That said, it does provide a hidden but easy-to-access spot to store the keys needed to loosen it up to make those adjustments. So, if you need to make those adjustments, you'll always have quick access to the necessary tools. Highly recommended for its price in particular.
