Basically, you do not much wrong, especially since the price is okay. I hold the mouse pad for all those handy where the USB ports are easily accessible and located as a small stroke can place on the table. I've been using it for besispielsweise USB flash drive, external hard drive and a small USB-LED-lamp. Although infected a blue LED lighting, which looks quite chick, but are not suitable in order eg to illuminate the keyboard under the pads. A separate on / off switch for the lighting or the device as such, there is not (for the latter one can pull the cable). The device is supported by Windows recognized easily as a hub (with me XP). The surface is good mouse-compatible (at least for my laser mouse), I have no "hanger" DS mouse. The edge of the pad is still low enough so as not to interfere (at least for me) on the palm. Which edge is the wrong word, because it is well-rounded acrylic or plastic. Nevertheless, the pad is of course higher than ordinary mouse pads. On the plus side is the fact that an extension cord with is included (length approximately 50 cm). The only real complaint I have is that something unusual small area of the pad. Especially those who like me have a large and wide screen, will often come to the edge of the pad during movement of the pointer from one end of the screen to the other, and then have to lift the mouse and start again. In this respect, the pad may not be suitable for action and skill gamers. For that, I give you a deduction of points. But in terms of the value for money I would recommend this device.
