The thing is, vaping can, does, become easy, once you shake out the hardware and find a liquid that works for you. I picked up a solid mod, no hardware concerns since then, got a second from the same vendor so my backup is an equally solid unit. Someone turned me on to a really nice carto, that's fine (and I have several others that are plenty good enough). Went with a tank from a vendor I trust, got rid of the refill hassles. Found one particular DIY blend that just plain works for me, and a couple others have started mixing it for themselves.
