Udo Nacke - X Con - Germany

Mac3 is the live evidence to disprove the occasionally heard pretension. Italian companies "don't work that hard" or "work less efficiently" etc. Mac3 has, from the very beginning, been very hard and efficiently working. Quality of the products has always been excellent. And "Mr. Mac3", Dott. Mirian Ronchi, has not only been one of the best inventors and managers but also a personality of charisma, warmth and last but not least humour that can’t be found very ofen.
