Count me in with the "unsanitary" crowd for the Dyson Airblade dryers. The water seems to pool up on the bottom of them, not far from where you put your hands when they're the deepest in. They do a decent job getting the water off and your hands pretty dry, however, I prefer the Xlerator hand dryers that many other theme parks have put in. They don't require you to put your hands inside anything and they have hurricane-force winds that not only blow the water away, but your hands too. Success! Xlerator dryers seem much cheaper than the Dysons ($450-$500 vs. $1300-$1400)...those Airblades aren't cheap!
