Eliminate the hassle of arriving at the airport with an overweight luggage. With TravelOn’s On Your Weigh Luggage Scale ($20), you can avoid the inconvenience and fees, by weighing your luggage in advance. Simply attach your luggage to the scale using the pop-out hook and lift with the two-handed grip. The weight is shown on the backlit display that also turns from blue to red when your luggage is overweight.
