My wife got me an Auto Dry a few weeks ago and tried it out today. I was disappointed only by the nozzle pressure (or lack thereof), but the product worked exactly as advertised. I'm not sure I was any faster though, if only cause I didn't have a nice bucket of bubbles to use with my mitt. I'm also worried about the dependency on Mr Clean soap and filters (as they warn anything else will cause self destruction)... although I'm hoping a store brand makes compatible soap and filters.
Cant you get your money back? Oh, and for what it is worth, I use the leaf blower to dry my car. Great for getting water out of those tough to reach places like fins, lights, and mirriors.
