DO NOT USE THE PROVIDED SCREWS
Color: Black
The screws they include are so cheap and they start to strip halfway in (even with pilot holes). The holders themselves are fine but now now the screws can go in or get out so it's either destroy the product or live with it. I used a quality screw on the one side and it worked just fine. Poor quality and not very thoughtful. If you buy, get your own screws.

Great for Docking Stations & Chargers — Not Just Laptops
Style: Deluxe
I didn’t buy this for a laptop at all—I specifically purchased it to mount my docking station and charger under my desk, and it works perfectly for that. The size is great, the shelf is sturdy, and it keeps everything neatly tucked away instead of cluttering up my workspace. If you’re looking for an under-desk solution for a docking station, charger, or other accessories (even if you don’t plan to mount a laptop), this is absolutely worth it. It cleaned up my whole setup. Highly recommend!

Didn't use for laptop but....
Style: Deluxe
Fantastic for my desk. I ended up using this to mount a Topping DAC under my desk and I used the side cubby to put my Google Nest Mini and Broadlink RF device. Got all that off my desk and everything tucked away just perfect. I haven't used the headphone mount yet, but I plan to use that to, low and behold, hang headphones! These are easy as heck to install and strong enough to hold up anything that will fit in the space for the most part.
