Ok so my next E-cig is going to be a 510. Has anyone tried the Revolver Gemini heavy hitter atomizer and if so whats your comments. Other than that I can't see why so many people swear by them guess i can wait and see when i get mine. How much liquid can they hold, how is the battery life compared to others, and is there any certain PCC that you should get for them. I'm currently using a Blu with the blue foam mod and the Volcano atomizers. The Blu pcc is nice but when im at work and go to charge a battery i leave it in the locker and sometimes come back to find that my battery is halfway drained because i forgot to take it off charge. The battery life for the Blu is roughly 30 mins of heavy vaping per battery and is there a PCC that prevents the draining of the batteries?
