I bought this scale a couple of years ago from AAA.  Have used it for maybe a dozen trips.  Then the weight indicator "hand" started to malfunction a bit.  Recently I lent it to someone and it broke.  When I opened it up to see if I could fix it, I found that there is only a small piece of plastic connecting the weight indicator to the metal mechanism that you hook the luggage to, and it broke.  Unfixable.  Pretty poorly designed.  Ah well.
