been vaping for a little over 1 month now with no relapse's back to the stink, i have been using nicocig comes with a cartomiser, nice and simple, thought i would try an upgrade and purchased the joyetech 510 with pre filled cartridge's and 5 spare's, my god they taste foul, if this had been my first ecig i would still be smoking roll up's now, i dont have time for all the mod's and cleaning so i am going back to the nicocig, not great but satisfied for 1 month, and they sell the refill's at tesco pharmacy, trying for a refund.
