To lay a network cable and then to crimp goes but really just ... I was told. And because this set is considerably cheaper than to let go so the expert, I ordered the Netzwerkwerkzeugset. And after several unsuccessful attempts then comes the moment when one is aware that one is smarter afterwards. Because the Krimpen simply did not succeed but had then ago the expert. And after I have compared his instrument with my set, I realized why it was felt that this was more toy than tool. Unstable and imprecise pliers, substandard connectors, etc. All in all, not even worth the shipping costs. ... But afterwards we know it keeps getting better!
