I was lucky and avoided the learning curve for the most part- starting with an Ego, adding a couple of Rivas, a box mod, and a black Silver Bullet. Lately, though, I've gotten the urge to try an automatic battery. I did get an automatic generic 510, but it has a really hard draw. So I guess the question is twofold. Are they all like that? Is there a particular brand of automatic that has a nice effective draw, good vapor and flavor? I understand that you give up battery 'stamina'. I'm not really worried about that since I've got lots of other equipment and am never far from an outlet. This is just something of a 'toy'. Also, I have no real concern as to what threading it is. I've got 510s and 901s and think I've even got a couple of 801s with an adapter I got to try, so I'm open to the best, most 'realistic' vape,
