Like I said the vapir one does work and will put out a few thick bags of vapor. Although it works doesn't mean its a good vaporizer. While it vaporizes good, the materials used are a bit hazardous to your health and counter acts the purpose of vaping. Even the v5.0 has a metal coil heating element, which releases ions when heated, also its case is still made of plastic which seeps out toxic chemicals when heated. It also has a lot of problems with the heating element and the fan craping out on them. The fan on my friend's bearing is shot and takes a second to get up to speed, when normally it is instant. They only come with a 90 day warrenty, and break frequently, not such a great combo. I would recommend anyone invest money they worked for on this vape, unless its free its much more worthwhile to get a different vape.
