Just tried it with my new hitch, & saved myself some embarrassment when trying to rent my first trailer. The key ring on it will help to store it somewhere readily available. Very easy to use, just plug in and have somebody work the turn signals and brakes. And at a very reasonable price. I would recommend this.
