I have 10+ days on them and after playing with different angles on my new NS Legacy noticed that a couple of the screws were becoming stripped. Sent an email off to the service guys and had a response within 2 hours asking for my address so they could send me replacements.
On one of the earlier days, I noticed that a couple of the screws came loose on one binding by day's end leading me to ensure they are almost overtightened since.
Also noticed more recently while in the lift line that the toe strap released as another poster mentioned on a previous run. No problems since.
Will check the straps when I get a chance.
Love the dampness and surfiness. Much better for me and my bum ankles than my Targas. Also noticed that I favor an alpine stance vs. a duck stance in this setup.
I've also had the stoe strap come loose but only once. I think if you adjusted it and it doesn't sit right perhaps there is play there? I'm not sure.
I haven't had a problem since on either of the 2 pairs I have.
