5.0 out of 5 stars Great locks, all keyed alike
Reviewed in the United States on July 9, 2024
Needed 3 locks for some outdoor stuff around the house. Having a common key is what I needed! These work great, and the weatherproofing is holding up well so far.

For $11 it is a great deal.

Would be difficult to cut off, but I would only recommend using it for a shed or loe security needs.

Comes with a waterproof seal for the key slot to prevent the lock from seizing.

Large in size and easy to lock/unlock.

I put up a new fence, I needed this for security around backyard, it's thick, it's heavy and it does the job.

Several reviewers have noted that the rubber shell fails to seal at several locations, making weather protection illusory. I deployed this lock to an outer fence gate, and it looked quite secure. A month later--without having unlocked the gate in the interim--none of the flaps will stay secure. Perhaps a burglar tried to defeat the lock? Maybe, but there's no obvious damage--the flaps simply no longer seal, and look pretty shabby, too. I've just reported the problem online to MasterLock, and I'll update this review to report how responsive the company is to this fairly frequent issue.

Gotta say that Master Lock was super responsive. I haven't received a promised replacement yet, but ML responded to my online support request within 24 hours. Their online support form wouldn't upload my photos, but I attached them in reply to their email acknowledgment and received an almost immediate promise that a replacement was being shipped. I'm adding a star now, and assuming the replacement arrives promptly, I'll up it to five stars.

5.0 out of 5 stars Perfect lock for what I needed it for
Reviewed in the United States on June 21, 2024
I got this lock for a dumpster. It’s very easy to use. This lock is good quality, has withheld its color and its quality through different weather storms (did not rust). It’s versatile so I can use it with something else in the future if needed

I like the plastic cover for the keyhole. I use it on my storage bin mounted to my dock on a lake. No rust and the mechanism is still smooth.

I can’t speak to the durability because I’m not going to try and cut it but seems sturdy enough. Like that it’s got a cap for the key way so debris doesn’t find its way in. Using to lock up my bicycle instead of a combo style. Key is way easier and quicker to open.

These are great heavy-duty locks with a hexagonal shaft to prevent people from using the soda can method of unlocking them. I highly recommend them but get spare keys before you use them if you are anything like me. Thumbs up!!!
