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.

Hides the cables
Size: 36", Size: 36"
Hides the cables. A little expensive but works well. When drilling the holes, be sure to be mindful of the overhang of the net compared to the brackets and the paper template.

Perfect for cable management
Size: 36", Size: 36"
I installed this on my uplift desk and didn’t have to drill any holes. I just used velcro ties on the support beams and it is holding steady. I have about 8 pounds in the mesh holder and the wire management for it is great. Easy to install and functions perfectly
