Auto-Blocking Belay device?

Been using my toucan for almost 2 years and it's not close to wearing out. I use it on rock, ice, sport, fat, skinny, rap, and auto block. It is the only thing I carry (with exception of gri gri on sport projects and rope soloing).

One time i tried to crater my partner with 30 feet of penalty slack but he's so badass he reached over on the way down with one hand and snatched the belay side of the rope stopping himself cold just past the 3rd piece. Haven't f'ed with him since.
