I love the DavidsBeenHere portable luggage scale! It is small enough to hold in one hand, yet it can accurately weigh up to 110 pounds! It is so easy to use. Just slip the strongly made strap on the scale through the handles of a suitcase or bag, press the button, and then lift the item. The ergonomically-designed handle allows for simple natural lifting motion. The scale lets you know with two beeps when it has successfully weighed the item. The weight stays on the easy-to-read screen a full two minutes or until it is cleared. It runs on an easy-to-replace lithium battery. It measures in both pounds and in kilograms. It shuts off automatically. It is so much fun, I was weighing everything in sight! After weighing my bags for my trip, I plan to take it to school to weigh my students' backpacks to make sure they aren't too heavy. This amazing item is indispensable for the traveler and others as well!
