I don't like it 
The breathing bit - the drip tip? Is that right? It's really big! I feel like I'm sucking on a large ice lolly or something! I've had a google to see if you can get different tips for it but I'm not having much success. All I'm seeing are ones the same as the one that came with it...
I've got 3 of the aspire e-pens and I really like the tips of those (flat, soft, rubber/plastic I think) but sadly they don't fit.
I think it's the metal putting me off as much as the size & shape. I also took delivery today of some GS-H2 clearomizers and they're okay... not fabulous but okay for the price... considering the nautilus was almost 10 x the price of one!
Am I doing something wrong?!
