Well i received my 510 9 days ago and i have to say the BEST thing about it is i have not had an analog smoke in those 9 days! i am very pumped about that.There are times where i have a little craving for a analog but it goes away quickly and are few and far between.I have been vaping as much as possible the same way i used to smoke analogs i go outdoors at home and work although i sneak vapes inside often at work now that it is getting chilly outside.I can get a full day out of a freshly charged batt and both attys working good.I can't say that i love vaping but what i can say is for someone looking to quit smoking and failing countless times the 510 has turned into almost a miracle product for me.To think that i have not had an anolog in 9 days is astonishing.The longest i lasted before my 510 was maybe 48 hrs. before going crazy and having one.I look at my 510 as a life saver and the best purchase i have ever made in my life! If you are here and smoking analogs every day FOR GOD'S SAKE buy AN E-CIG IT MAY JUST SAVE YOUR LIFE!
