As a test, I put the same size screw into where the shackle seats into each lock. On the old version of the lock, the screw almost disappears because the shackle seats deeply into the lock. On the new version of the lock, you can see most of the screw, because the shackle barely seats into the lock at all. The shallow seating of the lock shackle on the new version of this lock makes it more susceptible to brute force attacks, such as taking a wrench to the lock and twisting the lock open.
While I know every lock is not break-in proof but this model really takes the cake as the easiest. The mechanism is so easy to crack, you don't even need to be a Cat Burglar to open this lock within a minute. Trust me, set a combination, and just pull on it with a little bit of constant pressure, and spin the letter wheel, you can easily feel the wheel click at the right letters.
I purchased other Master Combination locks in the past and found them to be safe and secure, but this one just really is useless in security.
When unlocked the tumblers can shift your self set unlock code by accident. You can avoid by a few simple steps that I am quite surprised they do not state on the directions.
#1 - NEVER Scramble the number wheels when the lock is Unlocked.
#2 - NEVER Scramble the number wheels when the shank is moved to the 90 deg pass-code set zone - sure fire way to not know your code.
#3 - Set each number individually and check to see that the lock opens and closes between each number.
#4 - If your lock suddenly stops locking DO NOT adjust the numbers with the shank depressed in the pass-code set zone. That will constantly change your new and now unknown combination. instead - attempt to open the lock by adjusting 1-2 numbers before and after your original pass-code individually and see if you can get the lock open.
#5 - I would advise you to not leave the lock unlocked in a pocket or purse as the numbers may change inadvertently.
If the lock wont respond (stuck open or closed) the tumblers have been scrambled to a number other than your desired password - technically it can be cracked - but it is one in 10000 possible combinations - you might find it, if you were dedicated enough, but that likely means the lock is now junk.
Otherwise these locks should slow someone down if they are trying to get into your belongings. Well built and seemingly hard to crack without some persistence. Obviously anyone with a good set of bolt cutters will have easy access, but if you need protection from bolt cutters you should likely get a larger lock or maybe a steel door....
some people have been able to open/crack these locks by pulling on them and testing the combination - I was unsucsessful at doing the reverse to find out the code my previous lock was accidentally set to.
