While I've gotten the hang of cartomizers and ego batteries, I've never tried direct dripping. When I got my setup, I bought a kit that came with cartomizers and have never had just an atty to drip on. Anyhow, with my last order at litecigsusa, I picked up a cheap smoktech LR 510 atomizer and a drip tip. When it came in the mail today, I put three drops on the atty, threw my drip tip on, put a few more drops in, and boom! I got the most flavorful, nicotine laced vape ever! I actually caught a nicotine buzz! haha. Anyway, one thing I noticed, the flavor started to taste bad, so I tried to drip a few drips of a different flavor, but all I got was the first flavor again. Do I need to clean my atomizer? If so, how?
