Just thought I'd share my $0.02 
I actually still find myself removing the tip to drip, since if you are not in a stable position you will end up with a mouth full of liquid [insert "that's what she said" joke here].
However, it does have two features I've been hoping for:
Rubber washer, keeps a tight seal, unlike the plain plastic that wear down and gradually loosen up, which also forces any liquid on the walls of the atty back down.
Wider opening, so when you do get liquid near the top, there isn't enough pressure to suck up the liquid.
Since you were the first person I personally saw offering these tips, I will credit you with setting the standard once again. Cheers.
