These Rebuildables are NOT, and I repeat, are NOT for the beginner.
If you're interested in building your own atomizers, the first thing you'll need is an OHM meter. I got mine at Madvapes, but COV and other places carry them too. These are handy for cartomiszers, atomizers, and RBA's alike. It will not be a waste of money if you later decide RBA's aren't for you at this time.
Here is a direct link to the one I have. http://www.madvapes.com/cartomizer-and-atomizer-ohm-meter.html
These will help prevent mod mishaps. It would be a shame to short out your expensive to you mod, when it could have been avoided with a 20 dollar bill. It's money well spent. Even the storebought plug and play cartos and attys sometimes arrive DOA or DyingOA, or the wrong OHMS marked, and worse yet, a faulty coil causing a short... being able to check your ohms before mounting onto the mod will spare many springs and mods both.
Now that you're convinced you need an OHMs meter, and you are, in fact, checking out your cart, we can now get down to some basic RBA tutorial stuff. I am not a whiz, or a pro, but I do have a tad bit of experience, and am more than happy to try to share my journey with you., until a Pro does come along and hopefully takes over.
(please!).
