now, i am very new, and i have only tried one e-cig, but i love my joye 510! i had almost bought a blu, but everyone here talked me into the 510, im SO happy with it (besides a few atty problems that i have managed to fix). I am so glad i went with the 510, i get lots of vapor, refilling carts has become more of a hobby than a chore, to the point where i have decided to try making my own juice! i couldnt be more happy with the 510. people say it has a short battery life, but i have never run my battery dead (although my boyfriend has) plus with the PCC, and little carrying case for a fully assembled cig, it is great to carry around and he carrying case i can just throw in my purse and not worry about the button getting pressed. i would suggest you try the 510, its only $35 at cignot ($35 is only the cost of about 4 pack of cigs where i live!)
