Great! I'm speachless! There was a broken screw at my lock, and on behalf of the lifetime warranty, they sent me a new lock.

After my lock started jamming and became unreliable they sent me a new one. I have been using it for 5 years.

Lifetime warranty lives up to expectations, lock seized up after 3 years and replacement sent 1 day after warranty claim.
