I am finding sooooo many people on the forums that rant about the 510's being the best atty. My experience with them was not that great. I like the KR8's, in my opinion thusfar I get better TH and flavor. Since there are so many peeps out there that say the 510 is the cat's meow. I am beginning to think the atty I got must have been poor quality. So I was wondering where would be a good place to get a good 510 atty. Can you also specify what voltage you are vaping too.
