Absolutely solid!
Color: Black, Style: Fixed Width
I wish they made a longer version, because it's kinda pricey to buy two... but I made it work with one
I wanted a metal one that I could screw on so I didn't have to worry about it ever again... ever. It's holding everything and doing a great job at it.

Got Some Work To Do!
Color: Black, Style: Adjustable Width
Inspired by a kitten, I endeavored to clean up behind my audio desk, where a maze of wires is the picture of confusion, but apparently also a wonderful place to pull and tug, nap and chew ... so I got this. Then it sat there for a week while I thought about it. Felt complicated, organizing that big wad of a mess of wires. But when I finally got to it, it wasn't too bad at all, and the difference is huge! This item fit under the back of the desk perfectly and provides a deep tray you can immediately start to run wires though. Eventually you'll get there! Good luck!
