LOL my own personal opinion.... I MUCH MUCH prefer the Air Force dryers over the Double K dryers.... Professional handlers I know have a double k and when I am doing baths for them and getting their client dogs ready to go to shows I always use my Air Force dryer on them all.... these are Collie and Shelties I'm using it on.... on occassion an aussie or a border collie..... I think my air force dyer has more force than their double k.... and I can get the dogs done much faster with mine... and I typically will wash/blow out 5-12 dogs for them... depending on how many they are taking to shows that weekend...

I've had my air force dryer for several years... I don't remember what model or type it is.. its up in the kennel and I've been fighting off the Flu for the last week so I'm not gonna go walk up to the kennel to check right now LOL
