i got the master blaster in the last round of mystery boxes.......didnt think i would use,,,,but wall mounted it, the hose is 30ft.....washed my black on black 911 carrera easter sunday....used master blaster to dry and was EPIC....the amount of air it throws is nuts....if you don't clamp the hose tight to the bottom it blows off!!! its that powerful....i think its a must for any black vehicle....
i also have the handheld one that used last night to clean my mothers boxster.....good on her wheels and mirror and such but def not good to dry entire car
