Yeh, I have the Power Magic. I highly recommend it, as I also recommend wiring the camera to always have power. Reason: it takes about 30-60 seconds to power up from "off", and then sometimes a few minutes more to get a GPS lock. Which means you don't have camera coverage in parking lots, which is one of the common places people get hit (unless you wait everytime you restart the car, and which isn't optimal when doing the Timmie's dash-in-and-out on the way to work).
