I am vaping for three months now and find it much better alternative than patches and gum. I am using V2 and it works most of the time. Today on Twitter I saw the post about electronic cigarette blu for $1, the same advert is on this website. Two cartridges for $8.99 seems like the reason why electronic cigarette is this cheap but if it works it's still cheaper than smoking. My questions would be: is it a good product? How long one cartridge lasts? Has anyone tried it?
