For the re-wiring I did in my basement we used the push-in connectors for a
junction box. They worked very well especially given the large number of
wires we had to connect together. But what's the word on the street, my
friend who recommended them says that a lot of old-timer electricians don't
trust them, but that the journeymen that he works with love them because
they make their job so much easier. I thought it was great, strip the wire,
push the wire in the hole, wire's locked into place.
