The retainers are CNC machined to exact tolerances using CAD Cam software. All COMP retainers use only high

Comes with adhesive and screws. I chose to use the adhesive and it works great. My daughter got a Chromebook for school and its a great place to put it so we charge it when she gets in from school and remember to grab it before she leaves! Very easy installation, so far pretty sturdy, great price, and it fits perfect because you can adjust to whatever size you need.

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.
