A useful gadget that will be very useful both at home and on the go. I made the star dock because there were no instructions in my package, so it took me some time to understand the contents of the machine and how to use it. As the description suggests, a typical household outlet cord is fairly short. Therefore you need an extension cord. The cord for the car (when using a standard cigarette lighter) seems to be longer, but I haven't used it yet. So personally I would only recommend using it for smaller cars, but maybe not bigger than a mid-size SUV?
