This is the GSM version of the scales. Small enough to carry in your pocket and, as you are used to from the Nokia 'fridge phones' of the past, difficult to break. If you sit on this, the small digital screen will indicate that there is more than 200 grams on it. In any case, it will not break: this portable, pocket scale has a hard, plastic exterior that can withstand a knock. This way you can make the right assessment anywhere, really anywhere - as long as that weight is under 200 grams, of course.
