I got a pack at gotvapes at the beginning of February and an 808 to 510 adapter. I use them daily (mostly with my ego batteries) and 3 out of the 5 are still going strong. I absolutely love them- they are much better than the Clearomizer XL's. Here's gotvapes product description from my order form:
1 x GotVapes FLüXomizer™ CE2 CLEAR NoTint KR808 REG 1ml 2.6-2.8 ohm (gotvapes-clr808REG2.6-flux) = $8.95
1 x GotVapes FLüXomizer™ CE2 CLEAR NoTint KR808 REG 1ml 2.6-2.8 ohm (gotvapes-clr808REG2.6-flux) = $8.95
