This scale is almost indispensable, at least very practical! At home, the world can be like all the scale, with the risk of error due to calculation or lack of precision of the instrument (a colleague who was leaving with me in South America, made a error by calculating 10 Kg) On the spot, difficult to find scales! Several domestic flights with taxes in case of exceeding 2 per kg (10kg in the hold and cabin 5) and it is there that justifies the purchase. On return, several purchases have weighed the luggage and we facilitated burden sharing! This scale is reliable (I checked) and space-saving lamp is useful in troubleshooting. RECOMMENDED PURCHASE
