Grats!
BTW is you are using automatic batteries, for a spare think of picking up a V4L manual (V4L because they have the long cutoff of 10-13 seconds vs the 5 seconds for other KR8's. Try pressing the button 1-2 seconds early with manual so good vapor is ready when you start your drag, and let up right before the end of your drag). It's easier to get a good hit with a manual. Also try the cartos from SmokelessImage and Bloogplanet - they are bottom
coils and I thing a bit less hit (because the vapor is cooler when it reaches you mouth) but I think they give more vapor more easily. And I always use a plastic or delrin drip tip as a mouthpiece on KR808D_1 cartos like V4L and Bloog - wider stream of vapor, cooler on the lips, and easy to pull out to check or add
juice. I can get about 7 days use out of each carto.
If you find a manual V4L is not enough to get you off cigarettes totally, then you could try fat battery models with LR cartomizer blanks and atomizers. KR808D-1 (like V4L) is the strongest slim ecig so the way up from there is the big 460mah+ models that can use low resistance attachments fro more heat.
