God I'm glad they were there when they did! I used to use all my devices with bare wires twisted together, but my doctor said I had an irregular heartbeat from the constant defibrillation from turning on the lights and running the dishwasher. Had to go with this one instead and wow what a difference. No more electric shocks from bare bare wires! WARNING! THEY WILL NOT WORK IF YOU TWIST THEM AFTER INSERT THE WIRES! You can't just stick them in there and expect it to work, fun fact. This was my review of wire nuts. I don't know why Revane asked me to write about it, but it was important enough to write an email about it, so here it is.
