Ok so, sorry to be posting so much but all this information is quite overwhelming haha. So I just ordered an 808 from elitevaporworks which to my understanding is a 2 piece unit, meaning cartomizer instead of cartridge and atomizer correct ? Can you re-fill cartomizers ? How often can you refill them before you have to replace them ? I'm sorry if these questions seem redundant to some of you, but I just want to make sure I'm understanding so I don't break my new toy ! Also, what does a drip tip do ? Benefits of getting one ? Thanks for all the help, hopefully I will understand all this stuff before my kit gets here lol. ( Im totally confused by the Cartomizer, Atomizer, tank, Cartridge stuff lol )
