I'm not so sketched out about the size of the tip, but I really HATED metal tips and the way I vape, especially if they are too large, they end up coated in.... Something, hell, I assume it's e-juice but I was cleaning those suckers ALL the time. The Naut X comes with 2 tips, I'm assuming the other one is rubber or resin, and it stays totally clean and dry the whole time. I personally think it was a friction issue, and I now store my ecig in a bag in my purse so no gunk gets on it, but I noticed the difference immediately.... I think wider tips are great for DL, but not MTL which is my preferred option....
