Bought this after our previous hitch lock seized up and I had to cut it off. The first BP hitch lock is still functioning fine so far after a years use. Northeast, salted roads, saltwater. Will still probably seize up eventually. Locking it on can be tricky. Pushing it on enough and turning the key takes some dexterity. Put the R-pin in so it doesn't slide when pressing on the lock if you can. I always give it a good pull to double check it's locked on. Agree with other reviews that the R-pin should be stainless steel at this price point. Hopefully lasts.
