Hi everyone. I am a newbie and would appreciate advice. I am currently looking for a starter kit. My friends started using itaste vv but I am keen on Ego C. Can somebody let me know if the ego c 1000mah really has the variable voltage option? I saw that on Joye eGo-C 1000mAh Kit - The Digital Cig. I am keen on getting one with that option, else I prefer the ego c twist like what https://www.cignot.com/ProductDetails.asp?ProductCode=KIT-EBC-ALL has to offer. Which is better? On another note, any suggestion on where I can get an economy kit in case please? Many thanks!
