there are a few old threads on them. tldr: not made for the park and they need to be setup correctly otherwise youll be popping out of them every two seconds.
my personal experience is..ive got had three pairs of skis mounted with them (the shadow and carbon models). I've broken two toe pieces (literally the plastic cracked open). Both have been warrantied so the customer service is good atleast. I probably ski 80/20 all mtn/park now and I only hit jumps.
the reason i stick with them is because in theory they make sense. if there's a 1% chance they might work and save my acl one day it's worth the weight penalty and replacing them every few years when they crack. (I know it doesnt make a whole lot of sense)
