Well I started vaping, about three weeks ago. I had ordered a Joye 510 mega set and a ego clone with smartcarts. The only time I use the 510 is when I forget to charge the battery or to show other people. Most people I find, are drawn to the 510 at first, but I prefer a battery that will last me all day. When I'm using the 510 with pre-packed carts, I'd go through 2-3 carts a day. With the smart carts on the ego style atomizer, I can usually get through the day with using under 2 ml. The nice thing about the 510 and ego is that most accessories are interchangeable.
I had gotten some blueberry juice that was 11 mg , I was really surprised at how much I liked it and found myself vaping more for the taste and not so much for the nicotine. When I received a bottle of Black Cherry Tobacco I found the 24mg juice a little to stong, I cut it back to about 16-18mg with VG it seems to do the trick. I find it's nice to have some of my favourite juices at a low nic level because I can vape all I want. With the higher nic levels 18-24mg I get a little lightheaded if I over do it. I haven't had the opportunity to try a variety of flavours as of yet, Blueberry, HC#1 (tobacco), Black cherry tobacco, and B&H (tobacco). A word of advise, when you do order juice, don't only go with tobacco flavours (as I did), as it seems most of us move away from tobacco flavours soon after we start vaping. Good luck
