DigiWeigh boasts its DW-600W Wallet Scale is the perfect tool for measuring food at a restaurant when you're following a strict diet, ensuring a letter has the proper stamps at the post office, and weighing "other small objects." Which is basically marketing speak for: "drug dealers, this is designed and targeted directly at you."
It even includes a leather wallet with a clip on the back for keeping it in easy reach on your belt next to your pager, and a pocket for storing cash. For just $37 it guarantees you won't ever get ripped off on a back alley deal, and that you don't over-indulge on your carbohydrate servings the next time you're out for dinner.
