I don't know about you but each time at the check-out counter in a supermarket when the staff zaps the barcode-scanner too many times at a food product, it gives me the jitters. However, I console myself that their ls2208 scanners are probably safer than other brands that they won't contaminate the food they are zapping so many times at.
Bad enough that our greens are laden with chemicals from fertilizers and meat with hormones and whatnot, they even have to go through rays from a barcode-scanner! Am I being paranoid or what?! Oh gosh!
