Great for a gaming laptop!
Color: Black, Size: 1.37" without hook
Great product is you want to mount any size laptop under your desk. I used it for my Alienware gaming laptop and it's fantastic! The three points of contact hold the laptop securely, while allowing maximum airflow for the fans. The three "clamps" are rock solid and will definitely outlive the laptop. The installation was simple and easy, just need a drill.

under desk laptop system
Color: Black, Size: 1.37" without hook
Reclaimed real desk space with this one. The mount holds the laptop securely underneath without any vibration or creaking and the installation required no drilling — clamped cleanly to the desk edge. The ventilation spacing is generous enough that thermals stay reasonable even under load. Works with a solid range of laptop sizes and the adjustment mechanism is easy to use. If your laptop spends most of its time docked this is the cleanest way to get it out of the way.

Works great, but pads are peeling.
Color: Black, Size: 1.37" without hook
Works for what I needed, which was to mount my work laptop to the side of my desk. However, the rubber pads started peeling the first day. I tried clamping them down overnight, but they still ended up peeling up. They haven't come off completely and are still working, though. I may have to glue them down.

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.
