Indispensable for travelers, small and lightweight, fits easily in luggage. Very strong because at the time after more than 3 years no problem and the battery has not been changed. Very reliable, since the weight displayed is often identical to 100 gr near airports scales. Small problem: you have to watch the display simultaneously you lift the load, as the balance does not keep the weight in memory for a heavy baggage not practical at all. That said, good quality / price ratio.
