mda1125 your wrong
my friend has been riding these bindings for the entire season and i have the P1's with the same strap. he's probably been up 70-80 times and i've been up 24 times. neither of us have had even one problem with our straps. what happened is probably your own fault since when you bought them i'm going to assume that you adjusted them for your boots which means when you did you either didn't tighten them enough and they fell off or you overtightened them striped the bolt or the threads and made them useless. hope this helped people to not listen to this person.
