Given the very positive comments I fell for these 20m copper cable 100% quality ... that seemed nothing to say for the quality of metal, it's 100% very heavy copper and 2x2.5mm2 As against the plastic sheath is very hard, to the point that it is impossible to separate the two without taking a cutter son ... and the result is obviously very easily that bares a cable and then the other, what a pity , resulting in many missed and loss ... shame ...
I do not recommend this wiring ... and I regret my purchase.
