## Customer Reviews

### ⭐⭐⭐⭐⭐ Good lock, well built
*by  on Reviewed in Canada 5 January 2026*

Sturdy and lock still works after over 1yr of use. Even cold winter weather -26C.

### ⭐⭐⭐⭐⭐ This thing is a beast!
*by  on Reviewed in the United States 11 September 2022*

This thing is a beast! And first of all you're probably wondering "is this a real review?" Well you're dabbed straight it is! I've had this thing for about a year now, and it works great!Ive seen some other reviews and Let's be honest... a lock (any lock) is only as good as a thiefs determination. But it gives me piece of mind that my trailer is at least somewhat safe.But I'm writing this review mainly because, I lost my lock. I left it on my trailer bed and drove off and lost it on the freeway going 70mph. Well that was two weeks ago so I ordered a new one (thankfully I haven't opened it yet) and I'm driving today, AND LO AND BEHOLD ON THE SIDE OF THE FREEWAY, I SEE MY LOCK!!A couple u-turns later I pull up, snag it and there's barely a few scratches on it! I think to myself "well the lock has got to be broken or something" get home, pop in the key, and bam! It works 100% I couldn't believe it!Long story long. If you're gonna buy a trailer lock.... this is the one to buy!

### ⭐⭐⭐⭐⭐ Robusto
*by  on Reviewed in Mexico 31 January 2023*

Tengo 3 meses con el no se a oxidado con la lluvia, se ve muy bien por el momento
