Review on Portable Invisible Lightweight Ventilated Compatible by Nick Mosley

Overall good. Maybe a bit plasticky, but solid enough if you're not pushing hard on the laptop. They give the back the right height to make typing easier. My only complaint, however, is that the protective plastic on the back covering the black sticky material that sticks to your laptop is VERY difficult to peel off and often starts to peel off the real sticky material as well. There should be a small protrusion at the top of the plastic to aid in removal.
