I do see that the KR808 is 8mm shorter.
I still think I like everything about the 510 better though.
I can get a pcc starter kit with 2
batteries(1 for me, 1 for me wife), 3 pre-filled cartos, 2 chargers(1 for me, 1 for my wife), 5 empty boge cartos, and 3 different flavors of
eliquid for a total of $76
I figure I will do with it like I do my cell. Charge it at night, put it in my pocket before work, smoke on the way to work, smoke a few times during the day, smoke on my way home, smoke twice before bed, then put it on charge before bed. Then just refill it every few days or however often necessary.
My wife won't want to deal with all the bs so I will just prefill her cartos and end up buying her her own case too. Then all she has to do is give me her empties and put it on charge at night.
Is that a reasonable thought process?
