Good for dc power supplies
Size: 6ft, Color: Yellow, Size: 6ft, Color: Yellow
The AC outlets are very snug. I’m using this primarily for battery tenders and battery chargers; the outlets are spaced far enough apart to fit the dc power supplies and they stay in place even when mounted horizontally.

Cheap, looks good and works good
Size: 13"-32", Style: Dual Arms
Mostly painless install, packaging was subpar but everything works well. Holds a 27" monitor and a 24" monitor very well. Adjustable angles and hinges allowing for customization for your needs. Seems to be very sturdy and hasn't dropped since making sure everything is tight. Overall, worth it compared to more expensive options.

Sturdy, Extremely Adjustable, and Saves Huge Desk Space!
Size: 17"-49", Style: Single Arm
This WALI monitor mount is incredibly solid and handles the weight of my monitor easily without any sagging or shaking. The gas spring arm moves fluidly, making it super easy to adjust the height, angle, and tilt whenever I need to. Installation was straightforward with clear instructions, and it has freed up so much valuable desk space. Excellent build quality for a great price!

Solid Mount for a Large Monitor
Size: 17"-49", Style: Single Arm
Picked this up to mount a single 37" monitor to my adjustable desk and it’s been working great. The arm feels sturdy and holds the weight of the monitor without sagging or drifting over time. Installation was pretty straightforward and it gave me a lot more desk space compared to using the factory stand. It also moves smoothly when adjusting the monitor position or changing desk height. If you’re running a larger display on a standing desk setup, this is a solid option that feels much more substantial than some of the cheaper monitor arms out there.
