I got my 510 on monday that I got from madvapes. I have been suprised by some of the reviews on batteries not lasting very long I can go 4-5 hrs without charging and even then it did not seem to need it I just swapped the batteries to see if I saw a difference in vape and I did not I still got great amount of vapor and flavor. I have gotten 8 different refills of various flavors and very berry and redbull seem to be my favorite so far. Yesterday I started using it exclusively and it was a bit harder than I thought. I did smoke 5 analogs but tried to use the 510 more than smoking. Not bad considering I was smoking 1 1/2 packs a day for 20 years. Today I have had 1 analog when I woke up and vaped so far until 5 min ago I had another analog. I actually did not care for it and put it out half way thru and went back to the 510. We will see if I can make it the rest of the day with out an analog.
In the last 24 hrs I have noticed I have gotten some taste and smell back and my girlfriend who does not smoke has been more attentive to me so far
and has said she has been very proud of me. I will update as I progress.
