I have Burton Imperial's and Rome 390 Boss bindings as well.
One of my ratchets randomly stopped working last weekend. I'm guessing that the ice caused it to malfunction because it started working after my board/bindings were dry on the way home. I was extremely nervous about losing my board on the lift. Regardless, I am going to contact Rome and ask for new ratchets.
the only issue with mine is similar. when its cold the ratchet will not go into the grooves of the plastic piece. this could happened when u ride as well. My paint has chipped on my highback but thats about it . solid bindings just make sure u check them alot
