the Lap Chill Mat is covered with a kind of black neoprene. the support platform (25 cm * 33,6cm) for the computer is made of black hard plastic, not shiny. four rounded rectangular about 2cm * 0.5cm soft gum pieces serve as a bearing surface for the computer. this edition pieces are plugged with rubber stopper into the hole surface and thus changeable. the USB cable is attached at the back and almost 70cm long. the fan intensity is not adjustable. Overall, I am satisfied with the performance, even if it is only 4-5 degrees brings me. I could not imagine a more powerful fan (2 are in the device), but even without ventilation helps even at my computer the hole-like bearing surface. my mac airs louder than the Chill Mat. visually it looks good, is processed qualitatively and for a good price. I have deliberately etws a surface to work on the sofa and searched funktiniert outstanding. well right now.
