Of course, if you want to build your own coils on a rebuildable atomizer, you will need an ohm meter, kanthal wire, wicking material (silica, ecowool, cotton, etc.), and the knowledge to know what resistance (in ohms) is safe to vape on whatever kind of mod you are using. I'll spare you all that here, but suffice it to say, watch some YouTube videos. There are TONS of them out there. That's simply not what I want to talk about today. Maybe another day I'll do a step by step on my favorite, simple little coil. Today what I want to do is look at all six of the units in the IGO-W line and talk about their differences. This is not a review, as I only own two of them. But I've fiddled with most of the rest at my local shop and haven't seen anyone do a real comparison between them. So here goes:
If I were to order one today online, I'd probably start on eBay. Most are available through FastTech at even lower prices (like $7 for the original W). Kidney Puncher sells all of them, though you will pay a bit of a premium there, but not too bad.
