Fun and good little lock

Love this lock. Its fun to choose a random "word of the day" by scrolling with my eyes closed each morning and then opening them to fix it to the closest possible word. Keep it dry because they tend to go bad when left out in the rain.

Lock locked itself

this is a sturdy reliable lock. It is a step above key locks, and the old high school combination lock . However, it has its problems The lock locked itself into another combination and I closed it never to find the new combination Many times. Horrible. I have had to get bolt cutters from friends 4 times for these locks to get into my bags that I locked with my personal belongings I did not want stolen. That was $45 down the drain. They are sturdy but if you are being recorded, the numbers click so loud that your combination can be figured out if they know the numbers you started out from. And if people see the numbers on the other side of the lock they can see that and figure out your passcode. So you have to hide this in your hands.The only way you can guarantee it won't lock on you with a different combo is to test the combo before locking it. Make sure your numbers are on the right dial and check the moving arm piece isn't pressed down! If it is place your code into the setting and lift up pressing the lock up and down in the right combo. That is to confirm that your lock Has the right Combination and it will open for you the next time. Then press the moving arm in the lockdown position and change the numbers around. Test to make sure your combination is right. It should be now. I wish someone had told me this before I had to go through almost $50 worth of locks! Plus, the ones the seeds stole from me. I’m out $200 at least.Happy Zonningggggggg!!!

Not for arthritic hands.

Lock functionality is good but too tiny for my arthritic fingers kept falling out of my fingers. Too painful to handle. Ease of use is not good for arthritic hands, Durability and quality good,.no sign of rust, the stainless color is what I wanted.

Solid choice & reliable

I don't understand why there's so many reviews of people Unable to open their locks. These locks require you to set your own combination. The only way they won't work properly is if you do not follow the directions. Please read the instructions inside the packaging to set your own combination correctly. I ordered 2 master locks. I followed the instructions exactly and have not had any issues. I opened and closed mine 20 times each upon receiving my locks and setting my combo. No issues at all because I read the instructions. I got these locks for my pelican tool box at work. These are not for security but for privacy. These just detur people from easily taking my tools. Could easily be broken off if you wanted to. But I think they're slightly better than the other cheaper options on Amazon. Good quality for price

TERRIBLE LOCK

I'm writing to express my extreme disappointment with the recent purchase of a Master Lock. As a consumer who relies on the security of locks for storage units and other valuables, I was dismayed to find that the lock I purchased failed after only a few uses.Despite inputting the correct combination, the lock simply refused to open, leaving me frustrated and inconvenienced. This isn't the first time I've experienced such a problem with Master Lock products, and it's disheartening to see a brand that's supposed to signify security and reliability fall short in such a significant manner.Having encountered similar issues with this style of lock previously, I can't help but question the overall quality and durability of Master Lock's products. It's particularly frustrating to find oneself locked out of a storage unit or other important belongings due to a faulty lock.I urge Master Lock to seriously reconsider the manufacturing and quality control processes behind their products. As a customer who values security and reliability above all else, I expect better from a company with such a reputable name.In conclusion, I must say that this experience has left me deeply dissatisfied with Master Lock, and I'll be looking elsewhere for my security needs in the future. I hope that my feedback will prompt some much-needed improvements in your products and services.

Master Lock sets the Bar for 4-Tumbler Access

This is not advertised as an outdoor lock, but I have installed them all over the HOA where I live and they have not rusted, or declined in functionality. Master Lock has been around the block, as some, or maybe all of its sourcing from overseas. Many times this becomes the downfall of great companies, but Master lock as made it work. This one is a winner.
