Review on Portable Ergonomic Laptop Stand: Adjustable Height, Foldable & Stylish Aluminum Holder for MacBook & Laptops by Victor Hurvitz

It has good freedom of movement and good ventilation, but not very durable. I use this in front of the mixer and while it holds the computer in place any other range you set at an angle will move back and forth when set to that range. So if it's at 90⁰, it stays at either 85⁰ or 90⁰. Something can easily push it forward and your computer will either bounce off it or bounce off it.
