Quality product.
Color: White, Size: 1.37" without hook
First of all it's made of metal so, I won't worry about accidentally breaking it and dropping my laptop. It came with adhesive rubber pads that fit inside the brackets, which is a nice touch for helping not to scratch up the laptop. It makes a huge difference to help declutter the desktop space.

Satisfied my need.
Color: Black, Size: 1.37" without hook
Easy to install and my laptop fits solidly. I have a work laptop, tower and my personal laptop. I hated how busy my home office desk looked. Moved my personal laptop underneath and made a big difference.

Perfect for under table/desk mounting
Color: Black, Size: 1.37" without hook
Just what I neeed! These work flawlessly to hide your laptop from taking up desk top space. These do just that! They come with the screws needed to mount them, and the little sticky pade to prevent scratches on your laptop. Perfect Product! A+++

Good mounts but needs a quality improvement with the padding adhesive
Color: White, Size: 1.37" without hook, Color: White, Size: 1.37" without hook
Needs stronger padding. Falling off the next day. Press on, but comes off again. I should not have to apply my own glue, but it's likely what will be needed.

Desk Space Saver—Highly Recommend
Color: White, Size: 1.37" without hook
This under-desk laptop mount is exactly what I needed to declutter my workspace. I used to leave my laptop on the desk or shuffle it around, but now it’s neatly tucked away and easily accessible. Installation was simple—just a few screws and it was ready to go. The mount holds my 14" laptop securely, and the padding inside prevents scratches. I love that I can slide it in and out without hassle, and it frees up valuable desk space for my monitor and documents. If you're looking to streamline your setup, this is a smart and affordable upgrade.
