personally i've got them on 2 pair of parkskis and they're honestly not my favourite binding, perhaps because that they're kind of worn out and i need to pull the heelpiece up to snap into them, or maybe the looks, i dunno....
but i do know they've properly released on numerous occasions, they've been through hell and back and still work fine (except for the minor worn down heelpiece thats annoying to snap into) i've never ever broken a brake on these babies, and i bought them second hand with a brake missing and just went into the first skishop i found and they had a bag full of px brakes so they''re very common and finding replacement parts is also quite easy ....
they're a cheap undervalued binding that's honestly worth a lot more than what you pay for....
