510 attys are (for the most part) manufactured to standards. I've been using 510 attys and Cartos for more than a year on regular 510
batteries, Ego batteries, Passthroughs and various mods with no problem. It's usually the adapter you're screwing into that has the problem!
For example: I just purchased an 'Indulgence V2' from Eastmall that had a VERY badly manufactured 510 adapter. No Airflow!
1st: What kind of device are you using this on?
2nd: Are you using an adapter?
