I am quite new to vaping. I am working in Vietnam so the products are from Chinese manufacturers. But I think factories like cloupor and eleaf are O.K.- fingers crossed. Anyway I first had a style kL101 ecig and it was quite good at first, but when the coil head became old I replaced it with the spare that came with the kit, but the spare worked worse than the old one- so I replaced the old one again. I then bought an istick and a lemo drop rta atomizer. I am not totally happy with it because when you first vape on it , it seems to pop like a small explosion-it's only small but it's disconcerting and puts you off a bit from a relaxing toke. Also there doesn't seem to be much flavour of the eliquid or a nice taste in your head as you take a puff. Is this normal to backfire like that? After it pops the stream is quite smooth but there is not much flavour. I seem to get more flavour from the old one. Should I buy a different atomizer? I just don't know. Any advice or ideas. Darryn.
