I've used the ReadyBrake for about 4 years, excellent product. Easy to hook up, trouble free, good customer support. I had the box type previously and found the box cumbersome and it would wear down the toad battery. ReadyBrake does not affect the battery, as you are using the toad braking. I did order a new cable this summer as it was showing some weathering, replacing the cable was easy as it just slipped back into the sleeve all the way to the brake peddle. I had it installed by a auto technician as I was afraid to drill through the fire wall in the Saturn...everything was just so close together.
