Wouldn't open - needed bolt cutters

I bought this product several years ago and it worked well. However, I lost the lock and order a new one about two weeks ago. The new one was a dud. I used a couple times successfully. However, the third time I used it the lock seized up and I was unable to open it. The timing was pretty bad because I just got out of the shower and had all my clothes and valuables in the locker. I had to head to the gym front desk in a towel and slippers. I was afraid I was going to have to walk home in a towel and slippers and hope that I could get into my house without keys and cellphone as the gym was getting close to closing. Luckily the gym staff was able eventually open it by using bolt cutters. Now I am on the market for another lock and afraid of getting caught "naked" by buying another dud lock. Wish these locks could be more reliable, not sure what product to buy, any recommendations would be appreciated.

Best lock for the money!

Best lock for a small space. I've had several and will definitely continue to buy and recommend these.

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

For Privacy NOT Security

You will like this lock if you need it for privacy. It should NOT be used to secure a firearm, gates or high value items.I bought this for the purpose of securing car keys from the people who live in my house. I have a steel lockable ammo container. So basically its to prevent someone from simply grabbing the keys and readily accessing the cars. It will slow someone down but it wont stop them if they are determined.Remember someone with a long set of clippers can get into any padlock. However for firearms, gates or high value items I would suggest something more substantial.This is strictly a light duty lock for securing privacy but wont offer security.

Worked until I actually used it.

Worked great until I finally used it at gym. I reset the lock code to my own combo and tested it a number of times to make sure it worked. And it did until I put it to practical use. Once I locked it at the gym to secure my things, the combo suddenly didn’t work. I can only suspect that I may have inadvertently been pressing up against the latch, consequently reseting the combo without realizing. Feels stupid but I needed a bolt cutter upon my very first actual use for this lock. Therefore, I cannot recommend it. And yes I made sure my combo was lined up with the red lines.
