I initially ordered V2 cigs and they are great, cowboy flavor does come close to marlborough, other flavors are really good as well. Nicotine level is good , you know you are getting your nicotine. I prefer the manual battery with the button, better vapor. The V2 Power cig is great, plug into computer and it gives great vapor, my favorite. these are disposable cartridges, easy to deal with, have not tried E Juice yet.
Also tried cartridges from Cig Easy, they are aweful no flavor no taste and for 16 mg of nicotine,??...I do not think there is any in it.
Hope this helps someone.
