You know those people who embarrasses themselves in front of everyone at the airport by having their suitcases open on the floor, and frantically moving stuff from one suitcase to the other trying to distribute the weight and avoid paying extra for having one that is too heavy? That has always been my family! This little gadget could have saved us so much humiliation! I love it, love it, loooooove it!!!! It works great, it is very easy to use, and it is very accurate. What more can you ask for. Oh, yes! It is also small and light.
