Lately, weâve witnessed quite a few strange (unique?) USB peripheral devices and here is another one. This one is known as USB Boxer and is a USB add-on which will allow you to do bit of boxing practice with you fingers. This is like some gaming device (is it?) which when plugged to USB port allows user to use his/her fingers to beat the hell out of a speed ball. As per itâs manufacturers it is most advanced USB toy of this year and is fully interactive with graphics and sound. It also features game modes like auto, manual and keystroke and then there is an option of choosing ring time from 1 to 10 minutes. Each hit on punch bag will roll to hit counter.
