I bought three of these for each of the men in my life.  My sons don't travel as much as we do, but I told them to just put them with their luggage.  If they tend to over-pack, as so many do, a quick check before they leave will tell them their luggage weight.  When we have travelled internationaly, the scale is a popular item among the hotel guests as we pack to leave.  I could make $ on lending it out!
