Well let me know what you do, I would appreciate more feedback from other Vapor Bro's vaporizer use, the more we get, the better it will be for all.
I start out generally at 9(on 12 o'clock scale) and end up going to around 2-3 at the very end to get the last of it. Then I generally take out the weed and burn it(still gives you a good buzz)
Do you keep the hose on the vaporizer the whole time? I found I get better results if I hit it 2-3 times then take it off the ceramic heater to let the weed and glass cool, which lets the weed last longer.
