I have both kits and I gotta tell you. I didn't see a differance at first between the two. They both have excellent vapor. But the battery on the 801 is a bit squirlly. It blinks too much if you are inhaling for longer than 5 seconds decreasing your battery life. Also, if you shake the battery or move your hand suddenly, the led light lights up also decreasing your battery life. All in all, I think the 801 is a generic brand of the joye302 in which the joye wins. Also, the atty on the 801 burns a lot hotter decreasing the life of the atty. What are your thoughts?
