JMTandem's note about set and forget is somewhat correct. On the plus side, you can increase the initial breaking the moment your foot touches the brake pedal from moderate to very aggressive. This is extremely useful if you're doing a lot of highway driving; However, the moment you're exiting the freeway, you need to scale back the aggressive behavior of the controller or your brakes will lock up at slow speeds.
I'd agree, "somewhat correct". I've owned a number of Tekonsha brake controllers over the years - an awful POD, an adequate Voyager, a pretty decent original Prodigy - but for the last several years have been running a P3 and mostly let it just do it's job. However, even a great controller like the P3 needs to adjusted for highway use vs around town slow speed towing
if maximum performance is to be expected. I personally find Boost 1 sufficient for most applications but still adjust for heavier braking on the highway but do dial back for in town towing. That said, no brake controller can function with maximum effect if the trailer brakes themselves are not in good working order and properly adjusted.
