I really have no complaints about this item . This is a very solid well built lock that I bought to use on my semi trailer. I feel way more confident dropping my trailer with this lock attached to it . Very satisfied with purchase.

The lock was pretty great. I loved it because nobody can back up to your trailer and take off keeps your trailer totally secure and he’s gonna take you forever to have that thing off if you can get it off.

Easy to use and does exactly what it was made for. The addition of the orange chain for a visual reference that the lock is still on the RV is brilliant.

We needed to park our livestock trailer in the lot at the fairgrounds. We really wanted it to still be there three days later.It worked!Its easy to put on & take off. Its about the size of a jumbo coffee cup, so it doesn't take up much space in the truck.Well worth the cost.

It's the first time I've used such a device. We were getting ready to take a two month cross country camping trip. That ment, leave the camper unattended on unknown grounds. I wanted a bit of security.After looking around, the BOYISEN 5th Wheel King Pin Lock Solid Steel Anti Theft for RVs seemed a great match to my needs. Months later, now, and I'm still happy with the buy. This is an easy to use, sturdy additional piece of camping security.

Seems to work as you would expect, appears to be a solid construction. I’d be curious to see how much work would be required to get it off of the 5th wheel pin. Locking mechanism doesn’t seem to go to far into the pin relief, but it certainly at first usage seems sturdy and secure.
