Just bought a sp2 that I got on clearance from myvaporstore for like 38 bucks. I know nothing about this ecig, and was previously an ego/riva user. I like the idea of this ecig, but as with all ecigs, you have to learn about its quirks and idiocyncracies. I think I need to buy new batteries, as the ones I have stink. No prob, battery suppliers sell the CR123's for like 2 bucks a piece, but the whole thing comes apart and I've heard little blurbs about maintaining the button and the springs and keeping the connection area clean, etc. Just cant seem to find some general information.... HELP????
