I am totally happy with it and now that I've tried the menthol flavor I think I've found my flavor. Never liked menthol cigarettes but it's perfect for the e cig.
I can't stop sucking on this thing. Can I get a nicotine overdose???
I just got a KR-808D1 too. Like you I'm sucking on it constantly.
I realize now that I didn't order a strong enough dose of nicotine. How strong is your nicotine dose?
I've also found that I have to draw harder and don't get as much vapor when using the prefilled cartomizers that came with my kit. I also ordered some blank cartomizers and a small bottle of ejuice.
I put some juice in an empty cartomizer and found that a lot more satisfying.
Hope this helps.
