... What more do you want? The radiator complies exactly what he is supposed to do-namely my (Medion) laptop that especially in the lower left corner always has been very hot and be cooled at a super price! Although this I'm missing one of my 3 USB ports, but I can also reposition flexible. The toggle switch allows an individual on and off. the material promises some grip, rubber stoppers ensure a good grip of the laptop. How long all this remains to be seen. But for 2.99 I buy like a new one! Highly recommended!
