Reliable trailer lock for peace of mind
I feel confident leaving my trailer parked because this lock is tough and dependable. The sturdy build reassures me that my trailer is secure, and the adjustable lock feature is a real plus when dealing with different coupler sizes. It's a practical choice that has worked well for me.

Good deterrent to theft but...
Good sturdy lock and pleased with performance. It's a deterrent to trailer theft. Also recommend also using a wheel lock as well. The combo has seemingly stopped folks from trying to steal the mulch trailer. 🤞

Convenient and Secure Lock with Easy Key Access
I am amazed by how effortlessly I can secure this lock in place and unlock it with the key. It has been incredibly reliable so far, and I will definitely update if anything changes. Despite arriving slightly "opened" as seen in the picture, the excellent Amazon packaging ensured that all the parts were perfectly intact. I highly recommend this product!

Sizing before buying
Decided to buy three of these coupler locks for my travel trailer, jetski and dump trailer. However, during the installation, I could not get the one of the lock to fit on the travel trailer. It appears that the opening on the lock is 3-7/8” and the trailer coupler is 4”. Amazon buyers, be mindful the opening on the trailer coupler before buying this lock. Overall, the lock is good; bright yellow to deter individuals, smooth removal and installation. Only time can tell for attempted theft and weather.

Rusts quickly. Not overly secure.
It's a visual deterrent and only that. It cannot be considered an actual security measure. After less than 6 months it has already rusted considerably. It still functions but am rather disappointed in the overall use.

Great product
Fantastic, took a little getting used to using it.. but we have the hang of it now. We can leave the van and knew it’s safe to do so.
