I have a ReadyBrake and like it. I previous had a Buddy Brake, and although it worked I found it cumbersome to put on and off. I have never been stopped by CHP or any officer and have never been checked for a brake system. HOWEVER, should you get into an accident, your fault or not, it is conceivable that the other party will try to put you at fault for not having the braking system. Example, they made a left turn in front of you as the light changed and you should have been able to stop for your light which was changing to red. Normally you could claim right of way, may now not so much. Just saying.
I am one of the unbelievable stories, as my toad did break away, luckily on a back highway road, at a slow speed, not far from home. There was no other party involved as the toad just pulled away and slide into the curb when the mounting bracket failed. I did not have the buddy brake attached as it was a hassle for the short trip. Like I said at first, I now have the ReadyBrake and I don't move unless it is attached. Two wire hookup and off we go.
Happy Trails.
