Thanks for the cleaning suggestions guys... I'll give those a shot.
I bought two Aspire BDC mini novas and some spare heads on a lark, on the recommendation of my COO (who I started vaping over a year ago ). They are, in a word, amazeballs. Great vapor, terrific flavor, and affordable. They don't leak, they don't flood, they don't dry hit... if I wasn't into RBA's they'd be my go to vape no doubt about it. Even still, I bought 3 of the full Vivi Nova types and have vaped the hell out of them. Doing so right now actually!
I just dropped mine today and the 510 connection snapped off the base. (MVP didn't have a scratch) Serious bummer. I had to break out the Protank 2 again, and man, it's horrible.
I don't bother cleaning heads when I change the juice. The taste of the old juice is always gone after a few vapes anyway. I got about 3 weeks from my first head and I'm good with that for $2. I did dry burn it and rinse it in hot water for a couple minutes when it was obvious the coils were bunked though.
