Easy install.
Nice little lock. I was kinda surprised how it works with an internal screw lock. However, it's very easy to install and might deter theft.

Not a push snap closure, works well.
Fort time I’ve used/seen a lock like this. They don’t snap closed but screw in to close using the key. Different, maybe not as fast but they work fine for me.

Well made but too small
Well made but not wide enough to use on any trailer larger than a small one with small width hitch coupler where you use the lock.

The lock coupler works well on my utility trailer when I need to make sure it is secure on my vehicle. I do find the key/lock a bit tricky to remove the key from (stiff). Given the price and how I am using it - it does the trick
