Query: Poor quality

The lock itself seems sturdy enough, but its accessories are useless. The lock holder (to attach to your frame) broke after 3 rides, and the key seems fragile enough where I believe I could (and will) easily break it off within the lock; maybe that's why they give you 6 keys.Fat lot of good this lock will do me if I can't take it anywhere.
