免电池无线滑鼠
看到这个免电池无线滑鼠时，第一个想到的是会不会导致cancer？
Well now, our Battery Free Wireless Optical Mouse is, well, battery free! No batteries or in fact any charging method, is required so you can keep going and going at your convenience. This innovative new model is instead powered by its stylish mouse mat, which connects to your computer via USB. And once connected? An electronic field is generated around the mat which is where you smart optical mouse draws its power…totally wirelessly and battery free.
那个线还是有的，不过那个线不连滑鼠，反而去连滑鼠板。12.95英镑，也不便宜啊。
