I have this vaporizer (made by the same people) but i bought it at a local place. I'll post a pic of mine later. But this is the exact model. But anyway, you can usually judge how well it's toasting the weed by the amount of smoke you exhale. Turn all the lights off except one.

Then exhale in front of it. You should be able to see exactly how much smoke you had.

Also, when you dump out the "duff" you should be able to still find little green pieces. If it's REALLY brown you have it too high and you need to start out on a lower setting. I like to start out at a little less than halfway (my model doesnt have number settings) and as you hit it more and more, keep turning the heat up.

This way you dont burn it to start off with but as it's closer and closer to being cashed, you can go ahead and finish it off with some high heat. It's really all about playing with it and using your own discretion.
