Simple, reliable, and perfect for the gym
I bought this lock for everyday use at the gym and it works exactly as expected. The size is compact but still feels sturdy and secure. The combination is easy to set and remember, and the numbers turn smoothly without getting stuck. I like that I don’t have to carry a key around, which makes it convenient for lockers and travel. Build quality feels solid and durable for the price. Overall, a simple and reliable lock that does the job well. Definitely recommend if you want something small and hassle-free.

Functional, small lock. Meets expectations.
Lock works as it should. I'm sure someone could smash it open, but its perfect for a gym or work locker. Mine did arrive with some damage, a small chip. The combination is easy to set with the instructions on the packaging. Press down hard when the instructions tell you to press down. You'll feel it.

Works great
Works great, had a bit of trouble getting the code reset but it works perfectly for the front of my snakes cage. He’s not big enough to push the latch open but I have kids so decided to be safe!

Locker for work
Using this for work so it’s only used indoors. You can create your own 3-digit code, which is a major factor because if I can’t make my own code I’ll forget it and be locked out of my own belongings. Very easy to set the combination, and the instructions are on the package. I got the black and it’s a nice shiny black. Seems heavy duty in a good way.

The absolute best Master Locks
I've always purchased Master Lock product's. However, due to the rising cost of everything, I elected to purchase two less expensive brands. They were useless as they were made with very low quality materials and the combo disks were way too loose. I have now decided to pay a little more to get the absolute best Master locks 🔒. Stay with the best Master Locks always. Thanks for reading, an Amazon Prime member for over a decade. Captain Nihal.

Good but some difficulties
I use it for the gym so I don’t know if weatherproof. Lock ability is good. Color is good. Sturdiness is good. But all around good minus a little difficult to change the lock code
