Very well built item. Holds my 27 inch monitor with ease, has a great amount of flex and extension (it extends around 23 inches out). The swivels/movement/adjustments feel very smooth and installation was a breeze. I am a huge fan of MonTEK’s clamp mount, this is actually the reason I chose them over all the other competitors and I’m happy I did — no turning knobs, no parts sticking out at the bottom of your desk — very clean, minimalistic look with sturdy and reliable support. Do note that 1) There’s only 180 degrees of swivel in the arms/joints, which was a noticeable change coming from a monitor mount that had 360 degrees of swivel, and 2) You have to disassemble the mount to change where it sits/clamps onto your desk, which thankfully doesn’t make a big difference in my setup but can understandably be a deal breaker for others.

Amazing for heavy monitors

Color: White, Size: without USB

I had tried other monitor stands that claimed they were heavy duty, but this is the first one that stood up for my curved monitor. I did have to re-order as it was originally missing the hardware, but once I received it it was easy to set up. The quality is great and it moves very smoothly for day-to-day adjustments.
