This is ridiculously easy to fit. Works straight out of the box. Seriously, just split the chain at the quick link unscrew the bent one and screw this in (no tool). Rethread chain and reconnect chain link, job done! NB although SRAM says to use a new joining link each time you can get away with re-using a few times. New links are around four for £11.
