Im a user of the 510 atomizer primarily. I tried the 901 which didnt have any sort of atomizer funk to it like the 510s do when you first get them but they worked like crap. Totally anemic compared to even a regular 510. Are there any 510 ato/cartos that dont have primer? Or how do I find the best way to clean it? Ive tried using alcohol, water, and nothing really works foolproof other than vaping on that garbage until its gone (not inhaling though). This is by far the worst part about ecigs
