Quality lock
The automatic keyhole cover works really well. I think it'd be a challenging lock to pick. It's a great lock for the weight.

Sturdy lithe lock
We bought the smallest Mason for our 11-year-old son to lock his bike at school. It is compact enough to carry in his backpack and is easy to lock. Previous lock used had problems with the key breaking and wearing out. We are not afraid with the Mason for this to happen. The mechanism is foolproof and with 3 keys, you cannot get wrong.

Great D-lock
The Mason is a high quality D-lock that protects my bikes and seems better made than my On Guard locks. I like the feature that it holds itself together after being unlocked until you gently pull it apart.
