so far the best ecigarette in my opinion, for battery life and quality of vape it produces. this kit mixed with the variable voltage mega ego battery is a great mix too. that way you always have a battery to vape with. Holds quite a bit of liquid plus you also have the additional option of dripping on the atomizer if you choose. all in all a great purchase if you don't care about size too much to suffice for longevity of each charge on the battery.
