Great For Indoor Storage Lockers!
Works great for my storage units in my building, and my locker at work. Good quality, as expected from Master, and the keys are easy to hold. I like how the keys are the same color as the lock. I have three colors of the lock, so I always know which key opens which lock. Will buy anytime I need a padlock for any indoor application.

I like the way it’s made and how well it works. Nice and portable. Two keys are handy. Well worth the money.

Good lock great value
Master has always been known as a quality lock. It was a little bit smaller than what I had expected. As you can see in the photograph using a bottle of water as comparison. But it worked perfectly for what I had purchased it for.👍👍👍

Good product and what the locks are supposed to be for
This is perfect for school locker security. IMPORTANT: Master Locks are meant for low security applications! not high security applications. The reviews saying that these products are not safe don’t realize what the product is actually used for. They can be picked easily but for low security applications the chance of it being opened is pretty slim.

Works fine, but.....
The lock works fine, but's it's not blue. That's the reason for the 4 stars. It's advertised as a blue-colored lock (which is why I ordered it), but came in black. I submitted a replacement request and even commented in the feedback that the lock they originally sent me was black instead of blue. Amazon told me to keep the original lock they sent me and that they would send me another one, no charge. Well.....they sent me another BLACK lock. At the end of the day, it's a lock and it does the job. But, blue is my favorite color, and that's why I ordered it. They clearly don't have that color in stock. But hey....I paid for one lock and got a 2nd one free because they sent me the wrong color.
