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!

Good desk cable management

Bought this to replace my cheap 12" tray. Very sturdy. Was able use this to hide my power strip, usb hub, and thunderbolt dock from my table. Running all my cables through this. Fits well on my 60" standing desk at max length.

Solid and strong
Color: Black, Style: Fixed Width
It's strong enough to hold it's shape. I attached it with 2 screws, and was able to put 2 power strips inside.
It's a bit annoying to have the big "StarTech.COM" logo on the front, so I mounted it backwards, facing the wall. The whole point of a black tray is to hide things and blend in, not advertise for "StarTech"! So minus 1 star for that.
