I travel a great deal, domestically and internationally.  This product is one of the tools I keep handy whenever I move.  With the airlines' constantly changing policies and differing weight policies around the world, this luggage scale is indispensable.  It is lightweight and easy to store.  The only concern is that you have to lift and hold the luggage for a few seconds so if you are picking up heavy, you have to have some arm strength... or you friend/spouse has to have some arm strength.
