Self-Weighing Suitcase
I do not know if you ever take a plane, but if you loaded a suitcase usually careful not to exceed 20 kg. Each airline, in fact, has its limits to prevent anyone boarding heavy luggage. Increasing the weight of the cargo door to a higher consumption of fuel costs will cause problems.
Therefore, if your luggage weighs more, that cost in excess is usually done paying customers. The price varies between 5 and 10 € for every additional kg. To avoid unpleasant surprises could use a suitcase as the Self-Weighing Suitcase. Equipped with LCD, incorporates a rocker spring in the handle. This allows enough lift to read the actual weight. You can buy it for £ 69.95, equivalent to about 82 €.
