Calling all serious germaphobes! Forget all those hand sanitizing gels and wipes. And stop using wads and wads of tissue paper to open doors. Those who obsess about hygiene and germs can wave all their troubles away in 10 seconds with the Zadro Nano Wand. This scanner magically zaps E. coli, dust mites, lice, and fleas. And kills viruses and bacteria on surfaces. It only weighs 1.4 pounds, so it’s portable (though maybe not through airport security). The price isn’t all that high when you consider how much it will cost you if you get sick. This is definitely one gadget on our wish list until the health care system is revamped. [$143.99, Target]
