Sad to hear about how they're potentially infringing on your patent, Dan. And it's interesting that they would choose to use an apparently inferior material.. Anyway, as others have said, come over to the Vaporgenie thread and read the endless amounts of feedback, predominantly positive, about your vapes! I don't necessarily dislike the serpentine pattern, although I can see where it would frustrate the learning curve for someone who was new to vaporizing. The pattern is actually one the cooler parts of the Alivi8. Pardon me for getting more off topic, but I think if you want to make more money for vaporgenie then your number one priority should be getting a Waterpipe Vaporgenie out, simply packaging the glass vaporgenie top-filter with a bowl piece with a glass on glass joint. Many people (me, others, haha) have done this and it works very well, with very little learning curve, in fact far less than the normal vaporgenie and most of the vaporgenies because the clear glass gives immediate feedback as to vapor density. Besides that, I think you should focus on making a lower cost vaporgenie, even less than the steel coil, which could absolutely smash the vape market apart with a 25-35 dollar price tag. Pipe dreams, maybe!
