The first time I used an airblade dryer I thought, "wow, my hands are still wet!"
Then I learned how to use one.
(Which of course is a UX issue, they shouldn't need training)
That said, I think the original design wasn't too amazing, though it did look cooler than most of the existing dryers at the time. I vastly prefer the newer design (https://www.prodryers.com/Dyson-Airblade-V-Hand-Dryer-HU02-S...) which I think does a better job. And it's certainly harder to touch the sides which is a problem a lot of people have with the original.
