Ill check mine too.
Im on my 3rd broken highback and Ive given up on those stupid sticker pads.
My rear toe ratchet seems to be loose after every run now too. Not to mention the constant ice build up on the stupid circles in the footbeds and highbacks.
Its a pity I love them cause they really are fragile pieces of shit.
You might want to try lubing them. Burton uses very weak springs in the ratchets. I'm using silicone spray, works really well (it is a good lube for plastic/metal, gives a bit of water resistance and works well in the cold). If you buy some, make sure it's plastic and rubber safe (mine is intended for automotive use).
Silicone spray can prevent ice buildup as well, if you use it every few days.
