I've had my 510 now for about 3 days and I'm loving it. It is a bit different and I did smoke analogs at work today. I am making efforts to smoke only my ecig hopefully this week when my flavor and 5- batt charger comes in. I am / was a die hard pack and a halfer, even though I still hit the analogs sometimes I've had maybe a pack in the last 3 days since getting my 510. I love this thing, so anyone still on the fence, def try this. It is a bit weird at first and maintenance is a little cumbersome (batts, carts, etc.) I feel better all ready and I am starting to prefer the taste of my ecig over analogs. Plus I live in florida and now I can smoke with my windows up when i drive
. I look forward to my next flight.
