It would help if you could state what the specific problem is aside from what you tried that did not work well. Also which model of
ecig you use may assist in shedding light on the issue a bit as well.
Are they not wicking well?
Are they not giving enough vapor?
Are they not giving enough tatse?
Are they not lasting long enough?
Are they too hard to refill?
Have you tried things like the straw
mod if the issue is they are hard to refill?
Are you finding they just arent as nice as when you drip? (dripping can spoil us as I do not think any cart is as nice as a direct drip)
Perhaps you have a different issue than above?
The better you can descibe the issue the better we can understand and hopefully assist.
