It's not coming off the machine it's locking without a key or destroying it. For hobby lockpickers like me it's great because it's got the best core Master makes. Ok, that's not saying much, but seriously the 6-pin core on this thing is actually pretty good despite having been made by Master. This lock is harder to pick than an American 1100. Which, really, begs the question why their best core can only be found in a plastic lock when they've got locks that are invulnerable to any destructive attack short of power tools that can be picked by a 10 year old. But still, I think this lock is an essential addition to any intermediate hobby lockpicker's collection.

### ⭐⭐⭐⭐⭐ Lock out

### ⭐⭐⭐⭐⭐ Very high security (except the plastic parts)
*by I***T on December 29, 2017*

I bought this lock to practice lock picking. It was a great challenge to get into with its tiny spool and serrated pins. My brother is a truck driver and uses these on shipments that don't come with a seal. They're great for that purpose since they can't be shimmed open (ball bearing design) and are a bit of a challenge to pick. Of course, they can just be smashed open since the body is made of plastic, but that would leave a mark and let him know to report it.
