    Solid, Space-Saving Solution for My Desk
    Style: Deluxe, Style: Deluxe
    The Under Desk Laptop Mount Bundle was easy to install, but I recommend taking your time to ensure any connections to the sides of your computer can be made through the openings of the bracket. It’s important to double-check this step to avoid any issues with being able to plug in any computer devices, such as power, monitors, headphones, etc. In my photos above, I did not use the included hook or basket due to where I was locating my laptop under my desk. I was unable to attach the basket due to my connections to my computer. Note that the basket can only be added to the left side of the system. It would be great if the design were improved to allow the basket to be added to either side of the system. That being said, I do like you can choose to install the basket and/or hook, or leave them off. Even with this minor design flaw, this bracket is a fantastic space saver! This is perfect for my stand-up desk, and is a nice upgrade to my workstation.

    Likely the best underdesk laptop mount
    Style: Deluxe
    This product is actually pretty amazing. As a laptop mount, it is incredibly well designed. They have included foam padding strips for all the sides to protect your laptop from scratches when using it. They have also included a couple sheets of cardboard spacers, to use when aligning the mounting brackets. This makes sure you don't install them too tightly for your laptop, and it's a really nice touch. The side drawer is fully metal, which makes it really easy to magnet mount flashlights underneath for quick access. And the best part of all, they include 25 cable clips, 20 small ones, and 5 big clips. This adds incredible value to this package. One thing to keep in mind though, this product uses 3/4" long screws to securely mount under the desk. If your desk does not have a 1" thick tabletop, you may need to get some washers to mount the brackets, or else they will puncture through the desk board when fully screwed in. Be careful if using a powerdrill to install this product, because it'll drill so fast it'll punch through your tabletop before you can stop it. Although the product comes with 3M VHB for mounting, I wouldn't rely on that if you plan to put a laptop here. Your laptop's value is too high to take a risk using an underdesk mount that isn't properly held in place with screws. Despite that, I still highly recommending this product if you're looking for an underdesk laptop mount. The extras it comes with more than justifies the price for the product itself. Just be sure your tabletop board is thick enough to install it.

    Great product that's easy to install and frees up space on your desk.
    Style: Deluxe
    Easy to install. Nice quality product with good directions. Five out of five stars. Note that if you're going to mount a laptop, and cables will be running to it, make sure that the mount's vertical support features don't interfere with where your connector locations are on the laptop. I got lucky, ha.
