Super light! Very good condition, quiet, suitable for a 15 inch. Blue light rather enjoyable. No USB port loss. (Location to store the USB cable that measures twenty cm) My computer does not slip even if there is no anti-skid system. Very astisfait with my purchase, the only little thing that surprised me a little but will be present for all products of this type is the final height to what is found on your keyboard (PC + hightwise that of the support + a few centimeters if you use the 2 rear support legs for ventilation)
