I Have had these on my skis for a couple years now. I have the version that will slide forward and back on tracks to go from park to powder (they didn't have this as a selection for the review). These bindings are ok, but I don't think I would buy them again. I keep having to tighten the dins every few weeks to keep myself from popping out on routine landings. I think they were really solid for a while but now they are starting to go downhill after a couple of years of use and abuse. Overall a pretty good binding for the price though. And the sliding feature has come in handy a few times on deep powder days.
