I can give you the definite answer to your question! I have used a vapir 5.0 for quite a while although I did recently upgrade to a better vaporizer, I am very familiar with the vapir. The ideal temperature setting for the vapir is 360 degrees F. You simply preheat the unit to 360 F and then put your herb filled disk into the drawer and insert the drawer into the unit and either have a whip attached or a bag cuz the moment you slide the drawer in, you will start instant vaporizing. Make sure when you first fire the unit up that you have the fan setting set to high and then kick it down to the lowest setting. Use the middle fan setting to fill up your balloons as this gives a decent amount of vapor and towards the end of each balloon filling, kick it up to high to blast all the rest of the vapor out of the tubing. And make sure you have another balloon ready to hook up to the unit and keep the fan setting on low when changing out bags as not to lose too much of your vapor between bag switches. Also, ALWAYS LET THE UNIT COOL DOWN BEFORE COMPLETELY SHUTTING DOWN!!! It will fuck up the unit over time if you don't do this! hope this helped! Oh yeah, you can expect to get about 3 bags off of a gram of herb usually.
