I am not familiar with the system nor anyone who has one. However, for the $350 - $400 price to arbitrarily apply the trailer brakes seems a bit of overkill to me. And, depending on how sensitive the system is, one could wear out the trailer brakes in a very short time.
Seems only logical, mearly thumbing the manual braking lever on the electronic brake controller in the tow vehicle would accomplish the same thing ~ at no additional expense and only when the driver felt it was needed.
Then again, I have the Equalizer weight distribution hitch with built in sway control and even traveling in high cross and angular winds, have never experienced any trailer sway of an uncomfortable nature what-so-ever.
Just my 2 cents worth.
