Review on Portable Invisible Lightweight Ventilated Compatible by Robert Pearson

Very easy installation. They hold my MacBook Air at a comfortable angle for typing and browsing. I find them a little tricky to open as they sit flush with the bottom of the computer. Maybe it would be easier if I had longer nails. The computer slides easily when the stands are open. A major improvement would be some silicone/rummer on the legs to give a bit more slide control.
