I bought this product recently and I would recommend him to anyone laptop owners warmly. While I can not have any statement to make on the ventilation behavior of the computer, but to see the other review. I can evaluate it only by the practical approach to her and there is only one thing to say: 5 star and rightly so. American design, with - according to the manufacturer - lifelong guarantee, what more could you want. The surface is slightly roughened so that the device is not on a slippery slope, also removable and washable. Not to despise: the storage space in the hollow compartment in the middle, which I of course immediately for mouse and charger (can be clamped on the narrow side, so everything where it should) have used. The position of the laptop is ergonomically, so that you - in combination with a Swopper for back training - has the optimal computer workstation. To work in this combination is a must if one wants to prevent future back injuries. Conclusion: minor cause, major effect and the price is more than reasonable!
