5.0 out of 5 stars 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.
1.0 out of 5 stars 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!!!
5.0 out of 5 stars 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 Bolo. Good quality for price
5.0 out of 5 stars Highly recommend
Works great. Haven't had any problems. You can set your own code. It fits well with lockets and bike cables. Holds up well to being in the elements. Easy to open and close.
4.0 out of 5 stars Good lock if the application is correct.
Use it for the tool box on my utility trailer. It’s not the most robust thing I’ve ever seen, but it does its thing; keeps the honest person out. Like anything else, a set of bolt cutters will get it open. The combination aspect of it makes it easy for anyone in my family to access.
5.0 out of 5 stars Great Locks!
Very quick shipping, love these locks since they’re so easy to use whether you’re at the gym or need to lock up a shed! Very secure, these are very easy to program and use!
1.0 out of 5 stars Awful!!! Worse than high school locker. Spontaneous combo resetting. Super cheap construction.
Man oh man I wish I had checked consumer reviews on Master Lock's own web site before purchasing this. The look *looks* nice—but, the shackle latches into place with only about 2-3mm of travel, and is held in place by a very shallow metal well—there's no "hook" that grabs a notch on the shackle, like pretty much any padlock in the world. To be honest, it looks like something that would be easily breakable by anyone with so much as a wrench.Additionally—and this is the WORST PART—it is *incredibly* easy to accidentally reset the combination while the lock is open. There are countless users who have been unable to open the lock because the combination was accidentally reset while it was in their bag, etc. Most other set-your-own-combo locks involve a little more effort to reset the combination; this one seemingly will do it almost spontaneously.If you Google this lock, you'll find that people are able to bust it open with paper clips quite easily.Honestly, this lock is so much less secure than even your run-of-mill high school locker lock. Save yourself the money and avoid this cheap lock. Get yourself a Master Lock 175D -- it's more expensive but everything about it makes it a better lock.
5.0 out of 5 stars 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.
Candado oxidado y sucio.
El candado que me llego venía oxidado, sucio, así como si estuviera guardado en una bodega vieja por años, muy decepcionado de mí compra.
Pretty good, light-duty padlock
I have several of these locks that I set up with the identical combination. I used a four-letter-word (not vulgar), which I find much easier to remember than numbers.The padlocks are installed on gates and sheds around my property. They work reasonably well if you keep the internal guts lubricated. They are fairly light-duty; I suspect that someone could easily break in using a large screwdriver. However, they should at least slow the thieves down, which hasn’t been a problem to date.After several years of use, one of these locks just stopped working and wouldn’t open one day. I’ve read reviews that say they occasionally just don’t work with the set combination. I just cut it off and installed a new one. For about $10, I figured a cost of about $1 per year is reasonable.A decent lock that’s convenient to use.Regards, Mark
Simple, exactly what I needed
Bought this for a backpacking trip through Europe to use on hostel lockers. Worked perfectly. Did not encounter a single latch that this didn't fit perfectly on. Combination lock was perfect, since I feared losing a key. Found it tricky to open the lock in the dark since I couldn't see the dial, but then I decided to scramble the combo in a specific pattern, so I could align them by memory.This lock is not the absolute most secure option—obviously!—but it's perfect for a quick lock up and looks solid enough to prevent thefts of opportunity.
Bon cadenas mais choix de lettres peu adapté au français
Acheté pour un casier de collège, semble limite trop gros pour ça (4x5x1.5 cm pour la partie principale).L'anse se baisse de 3mm seulement mais a l'air bien rigide.La lisibilité des chiffres est moyenne, noir sur argent. J'aurais préféré une couleur moins brillante en fond.Les anneaux tournent bien, on sent bien les crans.Côté combinaisons, voici le choix proposé sur chacun des 4 anneaux de lettres:PRSTLNBDMJLHAEIOUYRTACDEORSTLNYRSTLNEDHKOn trouve 2 'Y' et un 'K', mais aucune voyelle en premier position, c'est plus adapté à l'anglais qu'au français.
