What's a kanger and evod?
Hi Jaded; I'm pretty new to this stuff too, but I started a month before you, so I'm a little further along in my search for the perfect e-smoke!
EVODis a type of clearomizer, which is the top part of an e-cigarette; the tank into which the e-liquid goes, plus the tip and the atomizer. A clearomizer and a battery makes up a complete e-cigarette. (There are other types of e-cigs, such as ones built around cartridges, but all I've ever tried is clearomizers, and i'm pretty happy with them.)
One thing I've learned is that there's no 'one size fits all' with e-cigs -- what works for one person might not work well for another person, for a number of reasons. So you've basically got to try out different things until you find something you like, but clearomizers are not expensive, and some of the parts have to be replaced anyways regularly, so experimentation is not all that costly (a lot cheaper than buying tobacco cigarettes!)
My E-Cig starter kit was an eGo-CC, which gave me great taste and thick, rich vapor, but it leaks likes like hell, and I can only really use it at home, pouring in a little e-liquid every time I want to fire it up. I've tried out some other clearomizers that fit with the eGo battery that came with my starter kit -- I got an EVOD, which seems to work well for a lot of people, but I found the one I bought to be leaky, and the vapor was too thin for my taste.
Last week I got a Vision Vivi Nova Mini, and I love it. Doesn't leak a drop, and the taste is great (although if you do a search of the Vivi Nova in this forum, you'll see that some people don't like them at all). I also got another battery, so that I have a spare (it's smaller than my first battery, which means it won't hold up as long in between charges, but it's easier to carry around).
Good luck, hth!
Regards
Glenn
