Pros - light weight, attaches to class one hitch, easy to use
Cons - install was slow - the hitch did not fit easily into the slot due to thick paint. Use wd40 and a rubber mallet to force in and remove several times to adjust. Also, the integrated bike lock cable is slight too short so you have force it over the locking peg.
