60+ days on these bindings used with La Sportiva Spitfires.
I like these bindings but have had the same "rotation issue" as most everyone else. I'm getting ready to purchase/add the Maruelli fix to them to help (and cut weight to boot). I am a larger guy with relatively flexible boots who likes to use the heel risers. I find that the 1st riser position causes the rotation most often (far too often, especially on side hill skinning) but it is very rare to have a rotation in the 2nd/top riser position ... so i often skip the 1st.
With all that being said: I've had no other mechanical issues with them, love the light weight, like not having a ski break, have used them with the Dynafit Ski Crampon (works great), have had them release when needed but never when unwanted. Personally, i like having the 3 heel positions and use all 3 regularly.
Side note: ski leashes. I use the Dynafit leash and attach it to my boot with medium strength zip-ties. The rational is it would likely break if caught in an avalanche but not a normal wreck or accidental release. No problems with this system so far.
