Welcome to ECF MadKat, and while I understand your disappointment I hope I can help you turn it around, at least a little bit. If the seller won't take your kit back (and he probably won't), you STILL made a good investment. Today you are learning you could have made a better investment, but what you bought so far was mostly education: you now know electronic cigarettes (PVs) WORK! And that knowledge led you here, to further your education.
My first e-cig was every bit as big a ripoff as yours, but I'll be eternally grateful I bought it because that's what it took to get me started from where I was to where I am today. I'm STILL not where I want to be, but it's a process & I'm delighted with my progress - and I hope you are delighted with yours as well. I don't know how much you smoked or how much cigs cost in your area, but the money I (over-)spent on my first setup was pretty quickly covered by the money I DIDN'T spend on analogs, and I didn't even quit the analogs, just dropped from about 30 a day to 6 or 7. So go ahead and do a "Happy Dance"! You've earned it by making your decision, and since you're here it'll just keep getting better. God Bless you, and Happy
vaping!
