When I first started vaping I was convinced that I would NEVER want to press a button to get my nicotine...that changed a week later when I ordered my ego and I never looked back to auto batteries. Manual 510 batteries are the way to go dudette. You have soooooooo many more options when it comes to atomizers, cartomizers, tanks, ect.
The KR808 is great as a back up device but I would highly reccomend you look into a true 3.7 device like the k go or e power 14650. Go to youtube and watch reviews on them...grimmgreen has a great review of the e power 14650(and 18650).
I know pressing a button to get your nic sounds wierd but you have to realize that you are no longer a smoker. I personally believe that getting as far away from anything cigarette related is a good thing. That's why all my PVs are mods...they look absolutely nothing like a cigarette and produce wayyy more better tasting vapor.
When I went manual battery from auto it took no time to get used to having to push a button to vape. If it does it won't take more than a day or so for you to get used to it. Also if you get something ego like you won't have to worry about charging your batteries every couple of hours. If you have any more questions feel free to ask. As I have said already go manual...it's the best way to vape(as you can see I didn't put IMO after that

).
