    Great fit and finish, quality hardware, well worth it!
    Color: Black
    Great product. It seem like it would probably fit most modern size laptops. He adhesive mounting tape seems very strong, but I used the screws for extra strength. Comes with it all…hardware and screwdriver. The plastic is quality and built strong. I had to trim on of the slots in the side to accommodate my computers plug, but that’s not the fault of this product. I would recommend this absolutely.

    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 shelves
    Color: C. White - Modern Minimalist Style, Number Of Shelves: 3, Size: 36inches
    These are a a great set of floating shelves! They were easy to install, feel sturdy, and look clean and modern on the wall. The set of three is perfect for displaying decor, photos, plants or small storage items while adding extra space without taking up room. Great quality, stylish, and a simple way to upgrade any space. They work perfect for my figurines to be displayed.
