My husband and I travel quite frequently. On our last trip on the way home one suitcase weighed in at exactly 50 pounds.  I am always worried on the way home that one suitcase may have more in it and will go over the 50 pound limit.  Not any more. I ordered the luggage scale and it is lightweight (so I can take it with me) and very easy to use.  I weighed my suitcases with the Travelon Luggage Scale and then weighed them on my scale at home - they were almost right on.  While I realize not every scale is the same, this way I can be pretty sure I will not go over the limit on the way home any more.
