The MasterNotepal - rests on a single, sandblasted surface of high-quality aluminum, a light material excellent for carrying heat off the laptop. You wanted slip-free comfort for longer use: we rested that surface on a wide, rubber-mounted stand at an ergonomically ideal angle of 8°, keeping your wrists free from strain. You wanted to extend your laptop life and get rid of hot surfaces: we added two silent 80mm fans that clip anywhere for targeting hotspots and dropping internal temperatures.
