I found I needed one of these when I got to the airport for travel and found my baggage was overweight and steep fee was imposed. After that, I felt that weighing ones luggage beforehand was a good idea. I liked this unit. I was accurate and quite handy to pack and take with me on flights, but it did not last. I did not think I was especially hard on it. I treated it well, but it did not last. I was most disappointed, but those are the breaks I guess. Your results may vary, but I replaced this with another brand from another source that was not Amazon.
