Started with an eGo Twist, moved onto a Vamo, and decided to purchase a Provari in order to stop the insanity! I have read too many posts from people stating they have purchased tons of mods they were unhappy with. Then, they purchase the Provari and find out it's superior to everything else. So, now I'm waiting for that bad boy to arrive. It should get here tomorrow or Friday! I feel like a kid on Christmas Eve!
