Multiple ports
Style: 20W_USB-C, Size: 10FT
The usb outlet broke within a week of purchase. The rest of the outlets work perfectly. Like that it has multiple ports to plug in.

Amazing. A bit of a job to set it up but worth it!
Color: Black, Color: Black
Excellent quality. Sturdy and strong. The screws that come with it are awful. Get yourself some different ones.
Takes a while to set it up and get it all measured. I did it while I was setting up my new Flexi-spot E7 Plus standing desk. Wanted to get it all done at the same time. At first. I thought it might be overkill, but I am sooooo glad I did get this. Now my computer moves along with the desk. It looks great. I bet it has improved the air flow around my computer as well.
Looks sleek and cool.
I might have set it a bit too tight around my case and as a result I have to shimmy it to get it out of the holder if I have to do any work on the computers internals. But at least I know it's secure. My suggestion would be to leave a little bit of slack to avoid this in your setup. Maybe like a 1/4 inch would be ok. The pads should hold it in place anyway. May loosen mine up if I find the time.
But it feels totally secure on the desk with no wobble or shaking.
Great product.
Also I'm a woman in my late fifties 😃and I was able to set it all up on my own. So don't be intimidated ladies, you can do it too.
I also bought two of the ultimate set up cable management trays. Great products.
Note for anyone from the Ultimate Setup company who might read this. Please provide better quality wood screws and some extra ones) I stripped three of the cheap ones that came with this. And it took forever to drill them in because they weren't strong enough. Then it would be perfect.

Awesome quality
Color: White, Color: White
Take your time installing! It comes with all the instructions and templates. Make sure you’re screwing this into solid wood. I would not recommend you hang your expensive PC from a particle board table.
My Pc fits in well and it’s compatible with a ton of different sizes. Mine has been mounted under my desk for about 6 months and is rock solid. I will say, mine is balancing in there. If I don’t have it at its center of gravity, it could tip out. You can adjust it with the various screw holes but make sure you mount it into something solid.
