Review: Worth the price - Great monitor mount. Held a G9 Odyssey OLED with no issues. There is no swivel support, but this is an excellent arm for the price. No sag and mounting it to the desk and arm is simple.
Review: Great arm, full support, amazing cable management - Super reliable, it is heave but sturdy, it gives you that feeling of security that your monitor won't fall off, I'm currently using a 49'' and I can rest assured that it won't go any where. On top of that the ability to hold more than one monitor is really desirable, really a space saver with a lot of cable management included in it. Something to notice is that this arm does not includes a vesa adapter to connect with the Samsung Odyssey G9 for example, that will have to be purchased separated

### ⭐⭐⭐⭐⭐ Very sturdy and versatile
*by K***S on December 9, 2025*

This seems like an excellent product. It’s strong enough to easily handle my 42-pound ultrawide monitor, and all the parts seem to be of sturdy construction while still looking somewhat sleek. After tinkering for a minute or so with the tension settings, it is very easy to adjust the monitor’s position. I particularly like that the arm connects to your desk with two separate clamps rather than just one, which seems to provide a very stable attachment. I’m not currently using this feature, but you can apparently attach up to three arms to the base if you have a multiple monitor situation (but not to exceed the stated 50-pound total weight limit).
