because Elitensmoke is new, I don't think anyone knows what model it is
If your cartomizers are 9mm diameter the it's probably KR808D-1 or KR808D-2 (each have different threads)
Here's the cheapest way to figure out if you have KR808D-1 -
buy a pack of these prefilled $7.50 prefilled cartos, the shipping is free. Do not try to force them on - if they screw in easily and work, the you have KR808D-1
KR808D-1 : BlueGrassVapor, Buy the Joye510, KR808D-1, e-cigarette accessories, supplies, and much more!
If those don't work then you probably have KR808D-2. To be sure, try these cartomizers

If you have KR808D-2 then that's the rebrander model. You can buy a whole kit for $37 at the second link above or a battery at the companies listed under the kit (except Bloog which now uses KR808D-1). And you can buy a D2 to D1 adapter at leCig to use KR808D-1 cartomizers like Vapor4Life
if you have KR808D-1 then you can buy single batteries cheaply at LiteCigUSA.net or VaporLeaf.com, or in colors at Vapor4Life.com and use all of the KR808D-1 cartomizers (no adapter needed). KR808D-1 is the more supported model that there are blank cartomizers sold for.
