Keenan Hoarwrote a review of Kuat Locking Hitch Pin on August 1, 2018
Familiarity: I've used it several times
Having this lock on my hitch lets me sleep without fear that someone is going to steal my rafting trailer, with my raft on it, or my bike rack with my bikes on it. Small and simple to use. I always keep the plastic cap over the lock so that it doesn't get jammed up with debris.
