Master Lock 150D Brass Padlock

See attached photo for size comparison in my hand, this is a solid little lock. It has smooth Tumblr action and the key slides right in. Not much more to say other than it works as intended and is a heavy little guy.

Not too hard to pick with a few weeks of practice, depending on the bitting you get. I've only been able to pick it once, maybe it was a fluke. I'm pretty new to lockpicking though

This lock is great for learning to pick security pins or for low security applications. If you are in to locksport, this is an orange belt lock that is fun to learn on. It has decent feedback and a satifying click when you open it. If you are purchasing this for use as a lock, note that it is not very pick resistant, can be shimmed and is subject to an overlift bypass using a comb pick. In other words it can be quickly and easily opened by someone with a bit of knowledge about locks. Ideal for low security or privacy needs but not a great choice when it comes to anything more.

I have always preferred Master locks, so choosing this one was a no brainer.

Most masterlocks are easily picked, vulnerable to bumping, or not shim resistant. This is the first one that I've seen that seems reasonably secure against such attacks.

Decent 5 pin padlock.

Good lock to learn lockpicking skills but a bad lock to actually lock anything up with

This is a nice solid lock that has good security.3

Lock received was exactly what was ordered. Works great.

excellent replacement for one I lost

An excellent padlock for learning to pick locks (as a hobby, not for nefarious purposes). As a lock, it's mediocre at best, as are all Masterlock products. They provide security insomuch as they are a visual deterrent to opportunistic thieves, but they are able to be bypassed in seconds by anyone with a few hours of lock pick training.

No issues and worked as expected.

This lock is good for beginner lockpickers, nothing else. Don't use it as an actual lock. It's super easy to pick.
