Digital Luggage Scale
The flight game is no place for guessing. The last thing they need is to show up at the airport with two extra t-shirts in their suitcase and end up paying those greedy airlines a small fortune in overweight baggage fees. A reliable handheld scale is the way to beat these scammers at their own dirty game. Just hook a bag up to the handle, hoist it a few inches skyward, and verify that they have the upper hand in this exchange.
