Review: 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. 🤞
Review: 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.

### ⭐⭐⭐⭐⭐ Awesome product
*by M***A on August 13, 2025*

I’ve used these for years on trailers and all have performed great with zero issues. It helps if you squirt some white lithium grease in the operable parts every once in a while to keep things functioning smoothly. Not a product defect, just the nature of storing mechanical parts outside and exposed to the weather.
