Rated 4 out of 5 by good product for price I paid seen to be what I paid for so far June 18, 2015
Rated 5 out of 5 by Does the job...easily. This lock is well made and is easy to use. Peace of mind, too. April 1, 2015
Rated 3 out of 5 by Not great but it works I have purchased a few hitch locks over the years, I would rate this one in the middle. Its light weight and easy to use, but then again most are. The problem is that the metal is very thin, while nicer in the sense that it can't be cut by a standard bolt cutter, it could easily be sawed off in seconds with a battery operated "saws-all." I suppose its only by keep honest people honest but its not a very secure lock. July 22, 2013
Rated 5 out of 5 by Excellent product. Works great.... good design easy to use. Very happy with the trailer ball lock. June 27, 2013
