This thing is a beast!
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!

This thing is a tank
Rock solid. I can't think of a way I could get this off other than messing with picking the core. Leagues beyond those crappy little yellow locks you see everywhere, and the best you can get unless you want to spend a fortune.If I was nitpicking, the lock core is what it is. Probably the best choice given the price range, and I'm not sure anyone is going to be out there with a specialized tool picking it anyway. One issue is that the little cover tore off its rubber strap but it's no biggy. I could see the lock having issues if I lost that cover and water started collecting in it, would be nice to have a tougher cover.
