As for dripping - I'll say that no Genesis atomizer or silica rebuildable has tasted quite like a direct dripped atomizer, for me. Not saying it's "better", but I get a different taste, and the vapor "feels" different out of a 510 or 901 atomizer. My favorite e-liquid tastes the best to me out of a high-quality dripping atomizer, versus silica or genesis. I believe it's a combination of the way the coils are wrapped, plus the wicking material, and the airflow.
Some people have qualms about spending 20-25$ on an HH357, and I get that, but there are other alternatives that are almost as good. A plain cisco 510 bridgeless atomizer is almost as good as an HH357, in my opinion.
On top of that, I don't get the whole disposable argument either - people spend tons of money on "disposable" e-liquid, flavor of the month rebuildables, premium drip tips for 30-50$, an ever revolving door of latest and greatest PV's, but somehow $20-25 isn't a well spent investment for 2-3 months? You can easily spend that much on a movie, or a crappy meal at a fast food place for 2 people. It's really not outrageous, in my opinion.
If you haven't tried anything as good as a dripper, then you aren't setting the kayfun up right.
Very easy to say that 20 bucks for a 3 month period is to much. I am a number person though. If I weren't I would still be buying juice at 10 to 15 bucks for a 30ml. I went into diy because of the numbers. That is also where I save my biggest amount of money. I spend maybe 5 bucks for 120ml making my own juice.
Last night I mixed a batch of 0mg. I am very close to being done with nicotine, very close. I can't sell a used hh357, but I can sell a piece of ss that has been made to become a rebuildable atomizer. It is all about perspective.
I agree with Ana, best 510 atomizer I have ever tried is the lr joyetech 510. Though I do not like the joye 306 atomizers, go figure.
