Master locks are best!
High quality. Durable and reliable. Previously saved a couple dollars on different brand…sometimes it would lock and sometimes not. Master brand is worth it!

Master Lock, the best of the best!
Life lesson: When you are in the market for anything, always go with the proven winner. Master Lock has long held the title of the King of Locks, and this lock is no different. You get what you pay for, and why risk buying some cheap knockoff to save a few bucks, go with the proven brand!

Work well! Keeps him out.
The psychopath was breaking into my garage, stealing my car and going joyriding while drunk. I didn’t realize this until he damaged the car and garage when he returned it. Ok. I suspected. Anyway I use two of these locks on the garage door rollers whenever I’m home. He can’t use his lock gun to open them because they are on the inside of the garage and he is not. The police department is essentially nonexistent. Locks work great! Good value for the money. Important that the hasps are long to fit the rollers.

Perfect for locking my box trailer and boat
Deep shank was the right lock

Funcional por el gancho largo, pero no tan seguro
Funciona para lo que lo necesito, pero no es una aplicación que requiera gran seguridad. Cualquiera que haya visto el canal del "lockpicking lawyer" En yt, sabe que estos candados distan de ser realmente seguros...

Garbage, shackle wobbles !
I bought the first one and thought it was defective so I returned it and they sent a replacement lock. When the 2nd lock arrived it was the same. The shackle wobbles back and forth about 1/4 to 1/2 an inch, unless you line up the shackle perfectly with the hole you have a hard time locking it. Time for Master lock to up their quality control. This garbage will be going back ! Don’t waste your money.
