This is my first post on here (long time reader) and my review of the oracle vaporizer, which I purchased about 2 months ago. I have previous vaporizing experience using a volcano. I waited to write a review because I wanted to see how it performed after many uses and I felt accustomed to it. The first thing I can say about the oracle is that it is fast to heat up, not ten seconds fast more realistically 30 sec to a min. I have found the best way to get it to correct temp fastest is to turn it on while Im grinding up the herb. Once its ground up, turn the unit off, add the herb, add the stack and bag, turn unit on and its almost instant vapor.
A reason I was drawn to oracle was the fact that not only was it fast but the way it was described it made it seem that the herb was constantly being moved around once inside the biomass bowl. This is not the case however, the herb gets pushed to the top of the bowl against the other screen, so it not in constant motion. I lift the stack off (with machine off) and push down the herb back down into the biomass bowl.
As far as how well its built, its ok. I think since this is the first generation, the next generation hopefully will be built better. For example the screws are not flushed mounted, its so ugly and looks like I built it in my garage. Again its not that big of a deal but for $400 its kinda lame. Also my temperature knob broke, it still useable but again it seems kinda cheap; its a plastic knob with a ss knob over it. As far as the internals I havent open it up.
The vapor quality, its pretty good. I would compare it to a volcano, not better! You can make it get extremely thick vapor clouds if you turn the temp knob to the red lines but at that point (according to the directions longer than 30 sec at that point) your burning it anyway. It does not do well with small amounts of herb either.
Usability is way cool. Its awesome how you can take rips as the bag fills up, works well with multiple users.
Overall has some awesome technology, infrared heat source,(superfast heat up) I think one of the few real all glass airway(most other glass airway vapes have metal bowls), connections from bag (fits in every bong I ever tried.) awesome functionality (ability to take hits as bag fills) combined with top notch customer service. I always receive emails back right away.( I havent tested to see how well the stand behind the warranty because I havent email them about the broken knob.) However it needs some fine-tuning. Better construction, better circumduction in the biomass bowl. I think that as time goes on as long as the reliability is there the Oracle will get better and better. I hope that I havent discouraged anyone from purchasing the Oracle because in all honesty I never write reviews for anything and wanted to give an honest review. I would definitely buy again because for me it preforms better than a volcano.
