5.0 out of 5 stars Wouldn't open - needed bolt cutters
Reviewed in the United States on December 15, 2010
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.

1.0 out of 5 stars Lock locked itself
Reviewed in the United States on April 20, 2024
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!!!

I bought these locks for my 11 year old daughter for middle school. I set the passcode for her and double checked each lock 3 times to make sure it would open. The opened without issue for me. However, she had to have them cut off of her locker within the first few days and she couldn’t open them. Not sure if it was a user error or not. They looked good and seemed sturdy.

5.0 out of 5 stars Nice size lock, 4 digit code is good
Reviewed in the United States on October 15, 2024
Need this for a gym locker, don’t want worry about carrying or losing a key. Like tgdd ed 4 digit code, I believe they offer this lock with alpha characters. I’m sure it’s not the most robust, bomb-proof, thief-proof lock, but it’s sturdy enough as a gym locker lock.

3.0 out of 5 stars Decent but it's too easy to accidentally change the combo.
Reviewed in the United States on November 1, 2024
This lock is almost good for low security needs but it has an annoying flaw that inspired me to actually write a review. To change the combo you 1/4 turn the shackle and press it down a bit. This is a motion you will do almost every time you use the lock so you must be ever-mindful of it. Also don't put it in your pocket while it's open or anything like that or you might mess up the combo and not even realize it.

I don't want to reset my combo every day that feature should be somewhat buried out of sight and mind (like we could use a little key or sim-tool to set it and forget it).
