I have been vapeing for about 3 weeks now. I have a 901.All I can say is WOW. I love the instant gratifacation I get. I still smoke my own blend of cig I make. I can definately see the appeal to an e cig. I deploy alot.I know I am going to get a good amount for my next deployment. This is truly a deplyable assets. LOL Keep on vapeing.
