nothin' is gonna be MORE accurate than the factory controller
OR the BRAKE SMART...they both use brake fluid <pressure>, not
VOLTAGE, or CURRENT to activate the brakes.
the brake smart is a TRUE progressive brake controller...apply
the brake a LITTLE (and hold it) and thats ALL the braking the
trailer will get.
the only other controller that comes close is the JORDAN
(which uses a cable).
i was stuck <brake smart was not in production> and for towing
my 18' car (flat) utility trailer couldnt wait....i went w/
a the Hayes Genesis (its one of the FEW controllers that can
display the CURRENT / AMP drawl...which allows you to determine
if ALL the brakes are working).
