Great Locks!
Love that we get multiple locks for a better price than buying individually. However, they do not get 5-stars, as there are only TWO keys for the THREE locks. To me, that brings down the stars, as there should be a key for EACH lock. Otherwise, sturdy, reliable locks.

Great Step Up for Beginners - Perfect for Yellow Belt Practice
I’ve gotten pretty decent at picking standard locks—usually, I can get through them in under 10 seconds. However, this Master Lock 140 definitely puts up a fight! It took me about 45 seconds to get it open the first time, which is exactly the kind of challenge I was looking for. The Highlights: Security Pins: Whatever is inside (likely a spool) provides great feedback and resistance. Rotation: You can really feel the core movement and counter-rotation, which is perfect for learning how to handle security pins. Belt Ranking: If you’re following the LPU (Lock Picking United) rankings, this is a solid choice for Yellow Belt practice. I’m sure I’ll get my time down as I get used to it, but I highly recommend this for anyone moving past the absolute basics and looking to practice their "feel" for security pins.

Good set of locks
Things have been picking up legs and walking off on my property lately. So, I have been doing anything proactive I can to protect what I have left. I actually purchased one of these locks to lock my riding lawnmower to a post. I may not stop a theft, but I'm going to try my best. Also one on my pool gate, and one on each on two shops or sheds that I have in addition to the regular door looks. It's nice that several came together in one set. They are not huge heavy locks, but they are fairly nice sized and they worked out perfectly and did exactly what I needed. I really like that the set all have the same key so it's easy to keep up with them, that was nice. The set comes with two keys, and the keys fit all the locks. So I'm not fumbling for a key on each lock and my husband and I both have our own key. The locks move smoothly and engage well. I've had no issues or problems with any of the four locks. Hopefully they will at least deter would be thieves. Great locks reasonably priced. I would recommend.
