I am convinced you get what you pay for in the realm of brake controllers. I am a recent convert to a Maxbrake controller. It is leaps and bounds better than my old Prodigy. It is one of the pricier ones but it can be fine tuned. Adjust once at setup, again when you initially hook your trailer and your done. For the first time I actually feel like there are decent trailer brakes behind me.
