This is just getting ridiculous where USB-powered warmers are concerned. A USB hand warmer is a USB hand warmer, right? Apparently not, as Chinese manufacturers decided to go up a notch by introducing the Professional USB Hands Warmer. Just how professional can it get anyways – just take a look and judge for yourself. Of course, it could be a play on words with the meaning that this pair of USB hand warmers will target working professionals at the office, although it does sound rather elitist as though other classes in the office are not entitled to such an accessory. $22.50 is the asking price if you want to look professionally ‘hot’ while working.
