Hello everyone, I am new to this forum and I wish I stumbled across you guys earlier. I bought a super vapezilla 3 weeks ago which is a total disappointment. Just like I read in one of the existing threads, the vaping session with the super vapezilla takes too long time. I also noticed it does not vape evenly the herb and I have to vape around 400 F to get a consistent effect (usually the temp is supposed around 375 F). It seems I can vape for hours and still have some greenish-yellow herbs. So I want to buy a new vaporizer, the most efficient one. I read in another thread that efficiency was more or less based on: using the least amount of herbs VS getting the most out of the herbs in a single session. My opinion is that if you can get the most out of the herbs than you automatically use less amount of plants. The factors to be taken into account are: - I prefer whip vaporizers - Convection is a must - Unhealthy material are not an option - Portability is not an issue. My aim is to find the most efficient vaporizer. Which one sucks out the most of the main compound evenly? With the super vapezilla some plant material were brown while others were still green. I thought it was me who did not inhale well but I had some friend try it with the same result!
