1. I had to go look. It's been 4 1/2 years since I first tried a cigalike - can't recall what brand but I liked it. Then moved on to egos with kanger tanks, then mods and rtas and I have never looked back. As I moved forward I gave my older gear to people who wanted to try vaping. Some converted, some didn't.
I used to track what my savings were but I am well set now with my kits and spend so little I can't recall the last time I bought gear, flavors, something - maybe 6 months ago.
