I'm relatively new to vaping, and the Blu was my first E-cig. My fav is the 510. But I'm trying to figure out what model the Blu is for atty/batt backup. I'm hoping that it's not specific to Blu as they're wait time for ANYTHING is horrible. Cheap, yes, but honestly I don't have the patience for a month to get 2 attys and a battery. Any help would be great!
