If you're the type who gets stung for excess luggage charges a little too often then this compact tool that allows you to accurately weigh your luggage at home or away might be of interest.

With an easy to read digital display, you attach the device to your bag, lift it up (it can measure up to 100lbs/44kg), wait for the beep, set the luggage down and read the weight.
