I wanted to love this device. When I first turned it on my thought was "you can probably dry a Boeing 747 in 15 minutes!" However, it proved less useful. I own a VW Jetta and BMW M Coupe. I wanted a device like this to get water out of crevices on my cars and my wife bought this for me as a Christmas gift. My BMW was in storage so I tried it on my Jetta. The conditions were 50 degrees and the car was washed outside and then pulled into my garage for drying. I used the Master Blaster to dry the car - and it took way longer that expected. So long that some of the water dried before I could get to it leaving water spots. I was actively moving the blower around and trying to be as quick as possible - and it still came short. If it were warmer outside, or you had to dryer your car in the sun - forget it! I think buying high quality towels, and using the smaller more portable version of this (The Sidekick) makes the most sense.

A few notes: This thing is super loud. I read another review where someone said it's quiet. I'm not sure if that person is deaf, but my 36 year old ears were ringing for quite a while after using this. It requires a 20 amp outlet. I connected this to a 20 amp outlet and it still blew a fuse. I won't hold either of these issues against it because with 8HP you should expect it to be loud, and the fuse being blown could have been a fluke.
