I have owned 4 of these locks; one for 7 years and it has been outside on the front gate to the truck yard the entire time.
It is opened and closed 1 to 2 times a day, with out any problems.
The other 3 are inside locks and have changed combos on them with out any problems.

Lock failed after 1 year (Yes, I wrote down the combo and used it successfully before)
By Timothy Lam
Count me in as another user that couldn’t open the Master lock (#177, same mechanism as #175) after it had been outside for a little more than 1 year (bought it on Oct 2008). Yes, I wrote down the combination and it worked several times before. It was used to secure my circuit breaker box which is on the outside wall of my garage (go figure why the builder don’t put it inside!) I only opened it when I had to reset a circuit breaker that was tripped and last time I successfully opened the combo using my written combination is when I had to turn off the breaker to replace my kitchen ceiling light fixtures. I was surprised when I cannot open the lock the other day (to reset a breaker) using the same combination that I have always been using. Needlessly to say I am not happy with the thought of additional expense and inconvenience of hiring a locksmith to open this malfunction lock…

Then I had an idea to look online for help and found out how easy it is to pick this lock if you happen to have the right tools (paper clip or a thin piece of metal). I tried the paper clip method for about 15 minutes and gave up. Then I found a video clip using a thin piece of metal and bingo! The lock opened right up after trying for about 10 minutes… I have never picked a lock before and definitely won’t try to pick one that is not mine, and you shouldn’t too. This is way too easy even for an amateur like me! I can’t believe it! What’s the point hardened steel and all these security feature to prevent cutting, prying when all you need to open this lock is a paper clip or a thin piece of metal? This lock’s internal mechanism is the same as the Master Lock Model #175 and it looked like this simple lock picking method has already been discovered since 2006. I can’t think of any good reason why Master can’t come up with a new design that can resist this type of picking in 3 years! I definitely won’t be buying another Master Lock again!

Excellent lock, hard to read digits in dim light
By Jonathan K. Perkins
I use a few of these for the gates around my home, and they seem to be excellent quality. My only quibble is that the numbers are quite small and difficult to read at night, even with my porch light nearby. The need to carry a flashlight pretty much negates the convenience of not needing to carry a key.
