Query: Good price, so and so performance

It stripped quite a bit of the copper off on 12 gauge speaker wire. I suspected first that the speaker wire was thicker than advertised. But it also stripped copper off 16 gauge wire by different manufacturer. I had to cut half way and then tried to pull the plastic off in order to avoid losing too much copper. My hand was sore afterwards.
