I think the lock set is well built and works well on my receiver and trailer. Not sure it would keep off someone that really wants to steal but it will slow them up some.
The lock and keys seem to work good, will have to see what they are like a year from now.
Not looped at both ends because to be used wrapped on bike and held so rider can release quickly. I'd prefer looped both ends for when I need hands free and don't want to tie it. Packs small so easy to carry.
The hitch is great but I installed it on a 2013 Polaris sportsman 550 eps and the ball is to high for the trailer to be latched on to it. Polaris put the muffler in the back and it is in the way. If you plan on putting this on a Polaris check were the muffler is first.
