All the review pictures of snapped-off keys in the lock are not encouraging.

Same, had to take an angle grinder to mine after about 3 years of use. to be fair though, I paid $19.

For this price, just know that the time will come when you have to devote 10 min to taking cutting it off or grinding off the rust to hammer it out.

put a bunch of thick grease in the lock. i am using one for many years now, in MN winters, full of snow and salt. just add grease in them every couple months and it will last for years

Good golly, maintain it people. Grease and various spray oils will keep it nice for years.

I have one that is 10 years old and still works and looks like new.
