I didn't even know these things existed until I was recently planning a flight and realized I had no idea what my suitcase weighed. In the wonderful world of airline ripoff add-ons you can't go blindly through the night wondering how much they are going to gouge you for your suitcase. This will save you an overage fee the first time you use it. A great product, this one is more expensive than some of the competition but it is more durable than my friends. It is very sturdy and I was even able to weigh a small package on it. A very good purchase that has the potential of saving you some serious cash.
