Just wanted to share my experience with the LR version so far. It's now going on 7 days and vaping like crazy, tons of vapor and good flavor, so far, the only cleaning I do is to blow it out from the batt end twice/day. I'm using mostly clear 70/30 pg/vg flavors. I'm tempted to give it a vodka and hot water cleaning but afraid it won't work as well afterwards, kinda like why fix it if it ain't broke! However, I don't want to wait until performance drops as it might be tougher to clean then. Any suggestions?
