Since I had to lay some power cables in the attic and in nei-built house of cards, and then connect and stripping the NYN cable just is annoying, anyway you cut always but a little insulation and the bare conductors looking through, I have to just bought not quite inexpensive stripper. As always about Amazon Prime the next day there, great service! But the thing is really worth the money !!! I never imagined how easy it is to lead stripping and then to strip the wires. Genial, something damaged by quickly, without pain in the fingertips and nothing will.
