We have had Dyson AirBlade hand dryers installed at work recently.
I had only use an AirBlade once before at the Goonhilly Satellite Earth Station on the Lizard peninsula and was impressed with its effectiveness.
They’re a very noisy hand dryer, but as you tend to only use it for around 10 seconds it’s not too bad. One thing I don’t like about it is that there is nowhere for the water from your hands to go except onto the floor (it falls to the base of the dryer then down either side). After an hour or so, the floor under the dryer has developed a small puddle.
However, they are effective and you always feel like your hands are very clean and dry when you’re finished.
