Review on Curt 51120 Discovery Time-Delay Electric Trailer Brake Controller: Enhanced Control for Towing Efficiency by Chris Litton

Amazing, I had to say that when I installed this controller. It was so easy to install. Quickly connects to the wiring harness adapter I bought from curt for my truck. It might not be as pretty as some of the other controllers, but thanks to its simplicity and functionality, it works great. Inexpensive, but it has two main aspects: setting the gain of the brake controller and how hard you want the brakes to be. It has a digital display so you know what the output is. It comes with installation instructions and how to set it up when attached to a trailer. It also has a small calling card to leave in your vehicle for quick reference if needed. Overall it seems like a great product.
