There is simply no better, safer way to dry the soft paint on our cars. I know people use their leaf blowers to blow the water off, but this thing was designed for the job. That being said, you MUST have a good coat of wax on the car for the MasterBlaster to work it's best. It's pricey but the time it saves in drying the cars, and not having to correct drying induced swirls is worth every penny IMO. I can dry the G in about 10 to 15 minutes including the door jams, inside the trunk and under the hood, I also blow out the interior and rarely use a vacuum cleaner. As a bonus I use mine to blow the dead hair out of my German Shepherd once a week, and to dry him after baths. Once again, HUUUUGE time saver. I know it's not a real technical review, but the thing just flat works, and it's super well made. This and the foam gun are two of my favorite purchases for taking care of the cars.
