I like the fact that this lock has a brass body and should be fairly resistant to the elements. Also, when installed, this lock will keep the honest folks honest. A determined soul can steal near anything, given time, but this lock should convince a thief to spend their time elsewhere.

I left my old one on the bumper. Just recieved the replacement. This lock is specific to the posi lock style where the latch is narrow. Good deterrent. Covers itself.Difficult to unlock at first try. Push the button as you turn the key. Keep it lubed with lithium spray. Hard to find in stores.

Fits my trailer neck perfectly and I can’t see a way it can be broken off. Only thing is watch it around salt water. It corroded the inside of the lock so it wouldn’t lock

I ended up returning this, sadly b/c it wasn’t big enough. Quality was great and seemed durable. Can’t go wrong with master lock.

The very act of purchasing a lock means you want to protect that item you are locking; don't scrimp and save a few dollars and buy an off-name brand, buy this Master Lock.Lost my keys to my other hitch lock and had to cut it off with bolt cutters; this Master Lock is to replace it. I have trusted Master Lock brand for 50 years, which influenced my decision to purchase this item. Solid, seemingly good quality, I'm sure it will work fine for years.

Like the title says. It was a letdown when a little percussive love tap didn't make this lock pop open like in the videos. Worse, even jamming a metal stick into it, fairly hard, had no effect either. No joy on my attempts to bypass the mechanism. I have yet to even successfully pick it, and apparently, there is at least one security pin in it. So, I got my money's worth out of this lock so far. I was kind of hoping for something that looks solid, but crumbles under pressure. This lock is actually pretty decent. Maybe I'm not hitting it hard enough? Time will tell. Maybe the earlier versions of this lock had flaws, but the current lock seems a little past me. I hope to get unreasonably good at picking it someday.

I lost the setpin for the last one I had, this lock works and works. Never jammed, never rusted, never failed. My fault I lost the pin in the first place. New one has a stop on the pin so it stays attached to the main body. With this mod, its perfect.

Good quality but the opening wasn't wide enough for the latch on my trailer. Send it back and refunded promptly by Amazon.
