You should consider that perhaps everyone else isn’t crazy. Dyson claims 12 seconds. Undoubtedly that is optimistic and many people will find it takes longer if they aren’t doing it exactly the way Dyson expects.

Personally I like the new air blades but also don’t find that they fully dry my hands. They get most of the water off and I move in with life. If I wanted my hands towel dry, I’m pretty sure I’d need more than 12 seconds.
