Even seemingly robust locks turn out to be startlingly easy to break off with a pry bar and leverage. So if someone sets their sights on stealing your trailer, it's probably a goner. Thus, I highly recommend that you use this lock in combination with storing your trailer in a highly visible, well-lit area. That way, most thieves will be reluctant to be seen working on it with a pry bar.
If you want something more secure, you're going to be looking at highly specialized coupler locks that weigh a LOT and also cost $250+. A few of those designs not only look considerably stronger, but are designed in a way that makes it much harder to pry between the lock and the trailer tongue.
As affordable options go, this is one of the better trailer locks I've come across at this price point. If you're looking for basic deterrence of the casual thief, this is probably the way to go. But again, I would use it in conjunction with storing your trailer in a highly visible location as well.
For the price, the security can't be beat. I like the contrasting red against the black trailer. The lock mechanism is smooth and never had an issue with locking or unlocking plus the sliding ball area makes it very easy to use.
This ball hitch lock is the ultimate poster child for "false security". Let me explain. I watched a ten-minute video on lock picking on YouTube. I then bought a cheap Chinese set of lock picks on Amazon ($8.00). I received the lock picks today, and decided to see if a totally inexperienced "thief" could remove this lock from my trailer hitch. So I went to work: It took me, at first, 60 SECONDS to open this lock, but after the tenth time I got it down to about FIVE SECONDS. Me, with ZERO experience. Imagine some scumbag who actually took the time and spent an hour or two at home practicing opening locks; it would almost be faster to pick than to use the damn key. What a joke.
I won't even go into its brittle, pot-metal construction, and its ability to be easily broken off by a simple hammer...
