the tube is so short that even if you place the arm all the way up, the screen is very low

Very good stand, supports the monitor perfectly, but you need to be careful with large monitors. Mine is 34" and somewhat heavy, it was a bit difficult to place it all the way to the right on the desk and bring the monitor to the center, it needed to be tightened a lot because it was slipping and falling, tighten it as much as possible, until it can't go any further, it's better if there are two people. I would like the USB ports to be a bit better, not just USB 2.0, but I have connected them directly to power and just charge my wireless accessories from there. It's not for hard drives or file transfers, only for charging or powering peripherals

Very sturdy and high-quality stand. I bought two... I have a 34'' monitor horizontally and got another one for a Samsung 27'' curved that I wanted vertically.
It offers any tilt the user wants, up and down, left and right, screen tilt in all directions and in suspension... It DOES NOT sag at all!!! Even when you try to turn it by hand, it's very difficult, as long as you've tightened the Allen screws. It includes EVERYTHING necessary in the package, screws, Allen key... very carefully packaged.

The product, although advertised for large screens, does not perform well. It has a very small vertical stand, resulting in not being able to fit a large screen on the desk. Additionally, it lacks stability on a large screen.

The base supports a Xiaomi 34 Curved. Excellent value for money! At first, I was worried that it wouldn't be able to hold it in place, but with a little more tightening, everything is perfect!

Excellent base. Particularly sturdy. It comfortably supports a 29-inch ultrawide, but it seems to have room for more weight easily.
Just be careful that the desk surface has a protrusion for the clamp to hold onto.

It has adapters for many different scenarios, so it will likely fit any monitor.

It supports a 32GQ850-B comfortably.
It has very good and sturdy materials, it doesn't bend at all even when I have the arm fully extended.
Easy to install.
-Height and tilt are adjustable with a screw (you have to loosen it, adjust it, and then tighten it again). Don't worry about something coming loose and it starting to fall.
The only negative for someone might be that the screws are Allen and not butterfly.
It's perfect, I recommend it.

Attention, the stand is not suitable for screens larger than 34''. The stand is for 34''-38'' (ultra wide) PC monitors and not for TVs. Here are the specs from the manufacturer's website.
