To help a laptop to a longer life, the purchase of a notebook cooler is useful. Especially if, like me, has the device are almost always on the legs while sitting in the evening on the couch watching TV. The device is intended to have a good cooling performance, easy to use and may be visually look even after what. Revoltec is in my eyes for the union of all these points. The heatsink fits 1a under 17 inch laptops. It cools the laptop so well down and also allows the legs lying such a good air circulation, the internal fan of the laptop has rarely turn up. In summer or when using the unit at full load the fan 3 of the heat sink can be easily connected via an included USB cable. The cable is always at hand in a small compartment under the Revoltec. A specialist on the other side can be used for small items (who needs it). The device is sure not the cheapest - but around a laptop to protect effectively and then to have something presentable, costs nunmal something. Revoltec is quality. This comes at a price. I like to be paid.
