    • Good locks
Size: 4 Pack
Works as a lock should, keeps the honest thieves out of your stuff. Comes with the “key” to change the combo and very easy to do. Haven’t ever had to cut one so I can’t tell you how strong it really is but I figure it’s about average.

    • Nice padlock for simple uses
Size: 4 Pack
Great padlock (relatively small so keep that in mind). Used it on both my UHaul containers (during shipping) and my Rubbermaid outside storage shed. For the Rubbermaid unit I had to enlarge the hole slightly in order for the padlock to fit. Nice value and great product.

    • Solidly built
Size: 4 Pack
We have a bunch of these things scattered across the landscape. We love that you can set the combination to whatever you want. That way we only have to know one combo no matter what we want to get into. They hold up to the weather well. No problems with rust or other corrosion.

    • Easy to set combination!
Size: 4 Pack
Easy to set combination. Works well exposed to weather. Not cheap, but they work well for my needs on my gates.

    • These work!
Size: 4 Pack
They have short comings for daily use in all weather, but those can be worked around. First the brass number wheels tarnish and get difficult to read. This can easily be cleaned off which I do about once a year when I lube them up and get them ready for winter. They will freeze up if wet when frozen, but fortunately they can easily be thawed with boiling water or lightly warmed with a propane torch. Once dry the cold doesn’t matter much. If really gummed up so they’re not relocking a few taps on the side of the lock will get it locked until you can clean it up! Towing as a trailer hitch lock it for hours through a blizzard didn’t change it’s normal behavior. A tea kettle full of boiling water got it unlocked and the trailer unhitched in record time. I continue to get good use out of these year after year! ... show more

    • There alright.
Size: 4 Pack
Work great, as long as you don’t have them outside. I use these for my gates. In the summer there just fine, but in the winter they become a pain, either they don’t latch or they get stuck closed.
