About Quallität the tongs need not write much. Simply Knipex flat (perfectly). I give "only" three stars because I am not convinced the crimping result. The ferrule is totally wavy after crimping. Although the sleeve sits better than probably possible with any other crimping tool, but the ripple-making problems. The ferrules Go to part then bad in terminals or ports. In double ferrules or two wires, we go with it really begins. Furthermore, one does not or hardly the possibility to compress with this type of crimping tool pressed core + shell again so that the cross section is even further reduced. Normally this crimps the ferrule, and then rotates again 90 ° and crimp it again. When it makes with these pliers, they forward as canker ferrules.
But that is purely subjective. Recommendation, PZ6 ROTO.
