Query: A Piece of Junk!

STAY AWAY FROM THIS LOCK. After only a few months of use, the lock jammed and I had to hack saw this lock off the receiver. Thinking that some water may have gotten in, I purchase yet another one and only used it occasionally making sure to take the hitch off the receiver and storing the lock in the garage. This morning, the lock could not be opened and I ended up grinding the bolt in two to get the lock off the hitch.I have other weather resistant locks for other applications that have been in use for years, without a bit of trouble.Reese...you have a problem which is only damaging your reputation.
