What is the best temp to use when using this machine while vaporizing bud? I am still not sure about how to use the machine to the fullest and would like some help from people who own one, so if you do have that brand and model your answers may not be helpful. Also, does the heater go off after like 10 minutes with yours or does mine have an issue? If you can will you just give me some step by step directions? please help or I willlose out on great way to get stoned
