Hi All - I have been vaping on V2 cigs for about 2 years now. I use the long manual 360mAh batteries with the refillable Ex blanks. The biggest complaint I have with them is their blanks go bad quickly. I have tried all the cleaning ideas of youtube, but still I can only get the blanks to last me 1/2-1 week before they start turning my liquid brown/black and stop hitting well. They are about $5 for one. I want to make the jump to a bigger ecig that last longer and has a better atomizer that doesn't go bad so quickly. I have seen some brands where you can just change out the coils which seem cheap enough. Anyone have any suggestions? What I want is a refillable atomizer that last a while and when anything goes bad it is easy and cheap to replace. I don't care if it looks like a cig and size is not too important. just want to switch to a better quality product. Thanks!
