The model I bought has a more flexible and just slightly lighter cable than the last, as well as much harder, more durable-seeming plastic around the lock. I like it better. There were two problems with the old one, that cropped up after 18 months of daily, outdoor use at the train station:
- The plastic bezel around the lock broke, exposing the metal lock.
- The metal collar inside, around the lock itself started to rotate, covering up the hole that the post was supposed to be inserted into.
Here are photos of the problem:
I think the one I just bought is a generation old, but it still seems better than the first one. These YPK “cafe” locks are nice because you can make two loops for flexible locking.
