Quality Product
Color: Black, Size: 6FT
Easy to install and comes pre-wired. This works as advertised and is easy to add to a new furniture build or retrofit into existing furniture.

Great for price
Color: Black, Size: 6FT
Worked great in the predrilled spaces in retail environment on counters. Had to do minor shaving of the existing holes but worked great after that. Only took 3 mins to correct. Well hidden and flush with counter.

Worthless
Color: Black, Size: 6FT
Would leave 0 stars if possible.
Things thing f****** suck!
Don’t buy them, don’t listen to the positive reviews. Don’t waste your money!
They don’t work. Charging ports shut off after you unplug your device. Have to unplug and replug in charging cables and ac plugs everytime you want to use them or else they won’t work.
Cheap unreliable product that matches the cheap price.
Spend $5 more and get a product that actually works!!!!

Perfect for behind the sofa tables.
Color: Black, Size: 6FT, Color: Black, Size: 6FT
Bought 2 for behind the sofa table. We now have a multifunctional table with charging ports and electrical sockets. The couch blocked the outlets, and now we are set. Basically, it's not only for desktop use....be creative :)
The pic shows holes cut in the table for easy insertion.

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.
