I started out around 5 months ago on the 510 and loved the vapor but I ended up changing to the 808 do to having to mess with the atomizer . I hated to mess with the atomizer and cart separately . So instead of going back to analog I switched to the 808 . That is what the wife was using . well this month the wife ordered a butch of stuff and it was all 510 . She messed up kinda . In the stuff was the 510 atomized cartridges . I get to use my old batteries and I have the adapter for the 808 to take the 510 atomizers . Well with the adapters everything is back to good . I love the vapors that come from the 510 stuff and now I have the best of both worlds . ROCK ON .
