You'll have to email the electricians if something like this comes out. After a long day of bleeding fingers I was looking for an easier way to tie the wires together. Found a metal drill, great idea, then found this a few days later - amazing. I fixed a box with an extra cable, short wires, in a hard-to-reach place using these connectors. They are really fast and take up less space. I will never use wire nuts again. I don't make whole houses, so cost isn't an issue for me.
