Has anyone used these before ? http://www.ecmweb.com/news/electric_nonmetallic_cable_splice/index.html

Today I watched one of our jouneyman install these on a 12/2 cable. Then I was asked to connect some more. I cannot believe these things are UL approved for residential in wall splicing! The only thing connecting each conductor was a flimsy thin looking "U" shaped piece of metal that the conductor gets pushed into. I actually felt guilty leaving the job knowing that these inferior connections were left inside our trusting customers walls. After telling the boss my concerns he just said: They are code complient... If I was running the show I would have said NO WAY - do it right! Anyone else use these before and what is your opinion regarding them?
