I have an MFLB which is a currently best-selling portable vape. Just to travel with it, I had to get a small tube that I could fill with ground herbs. Then I have to grind herbs and fill the tube for travel. Then for every 5 hits, I have to unscrew to tube and dump another pinch in to the vaporizer, often spilling some. I can't easily share it because there is a learning curve. And I have to keep seperate re-chargable AA battaries on hand to power the thing. I have to push a battery onto the connecter for every hit. People Love the MFLB, I like it. But it has so many problems that the CannaCig doesn't have. Internal Battery for 300 hits. Internal cartridge for 40 hits. Easily shareable. stealthiest available. I want one.
