Good to see someone else got theirs. Thanks for adding your take on it. I'm not sure why you wanted it to get 10-20 degrees hotter if you also say that the air is too hot. (Which I happen to agree with!)
Because then I could take drags with higher frequency. I suppose I left out the fact that you have to wait for the thing to heat up and start producing vapor. You can't take a drag every 10 seconds... nothing is there. Have to wait about 20-30 seconds between... thats when the air gets hot. Waiting longer made me cough on occasion. I think if it got a bit hotter I could vape it with higher frequency, the aluminum and vaporant would get the majority of the heat while the air (if hits are taken frequently enough) would not take on as much heat because new air would more constantly be filling the chamber. I don't know just a thought.
In the current design lengthening the mouthpiece could help my allowing the vapor to cool a bit before it hits your lungs.
