I have the attachment, and I must say, I use my $10 bowl diffuser way more often than the devafuser. I should've taken it back & got a refund, but I procrastinated and now I'm stuck with it...The bowl diffuser just works better for me, it dries much faster than the fingers. It does seem like a great concept, so of course i had to have it, but it's not better than the bowl for me.
