This is such a cool little item!  It's well made and sleek and appears to be something that will last!  As usual, I read a bunch of reviews before purchasing.  Someone took the time to take this baby to a shop and get it calibrated and it was within ounces of being accurate.  For my money, that is great!  I don't want to get any closer than a few pounds to that magic 50-pound cutoff, so ounces off, if it is!, is a non-issue.  I even bought 2 extra for my kids who live in Europe and travel constantly!
