Maryliz, I've been smoking for 30+ years, and I was smoking over 2 packs a day until I started vaping about 3 weeks ago. I'm vaping V2s at the moment, but they aren't strong enough to get me completely off the cigs (though I'm down to around a half a pack or so), so I just ordered a E-power kit from CCV (I can give you the link if you like). It's essentially similar to the KGO, except they don't come in pretty colors, lol. That and as Jay pointed out, cheaper to replace as things go wrong (for example, if the switch goes, as just happened with one of my V2s, I can just replace the switch for under $10; if this happens with a KGO, I'd have to replace the whole thing, at almost $25). If you want to go the E-Power route, CCV has better prices ($57, plus free shipping, 5 blank lr cartos and 30ml of juice). As far as juices go, I recommend trying Highbrow, his flavors are exceptional!
