It was pricy, including the indicator light in the cabin, at about $1,200. The only drawback is it cannot be transferred to another toad.
Took a while to get it adjusted to where we could just feel it kicking in when we pressed the brake. However, ours does not come on (you can hear the pump) when our turn signals comes on. Maybe there is a wiring issue on your unit.

I have two toads and that is one reason I went with RVibrake. Very simple to switch between them or to move it to a new vehicle. The setup is pretty simple and the brake vacuum is released automatically. I understand that their newer unit has a tire pressure sensor built-in which could be handy.
