I picked up a joyetech eRoll 15 days ago from extremevapor in Colorado Springs. This choice was based on the recomendations of the store manager. I was a 1-1/2 to 2 pack a day smoker, and I have smoked for over 50 years. I do not like the eRoll, I LOVE IT!!! Using 24mg nicotine (based on the managers suggestion), I have been completely tobacco free since getting this device! First thing that I have used that has ever worked for me!
