Same here, I've watched that video about 10 times. 0-190C in 4 seconds... now that's instant warm up. And using a single AA battery... If this this thing is half as awesome as it sounds the inventor(s) win a FC Nobel prize. Very cool! Can you explain to a non-scientific mind how the convection is taking place when the user isn't drawing in air? Something to do with the difference in temperature between the heating element and the glass? 0.04 - 0.09 grams per load sounds good, many of us appreciate small loads efficiently heated. How would you describe the taste compared to another vaporizer you've tried?
