Here is a Janty Stick electronic cigarette review by two pro vapers from Vapor Talk:

One of the reviewers says that he believes the Janty Stick produces a little more vapor than the typical pen-style electronic cigarettes perhaps because of the extra power that it gives. The Janty Stick also comes with a nifty safety feature not present in other electronic cigarettes.

It has a built-in USB passthrough so you can vape while charging it via your laptop. They declare the Janty Stick as the most versatile electronic cigarette that they have found yet.

They also say that the pictures on the Janty site may not do this product justice because the Janty Stick looks big in the pictures but it is actually very small. One can easily cover it up in their hand. The box-type design is also an advantage when you are out in public vaping. If somebody confronts you, you can always make up an excuse that it is a personal inhaler or asthma inhaler. Most of the time though, you have freedom to vape in places where smoking is banned.

Being a universal device with complete features, Janty gets ahead of the game with the Janty Stick.
