Just read your post Bonné. Don't be discouraged bro. With every new vapurizer a learning curve is unavoidable. :thumb_up:

I would stay with 2 screens tops like DansMaTete said since more resistance is created when more material needs to be heated. That is why i haven't been happy with my modified screens and ordered new original ones since they seem to work the best for the batteries that are provided with vaporizer. I think the adapter that they sell could be better solution when using 3 screens but i will wait a little bit longer with the purchase until i do more tests. 

I have vaped 5, 10, 15 and 20mg with no problem with one and two screens. Divide the amounts between the two screens and experiment with the time of heating. I apply the heat and as soon as i see it being vaporized i release but then apply again after couple of seconds while still steady inhaling.

I don't know since there are so many factors in play but i tell you i was feeling everything from 10mg onward. :!:

Man i would really feel bad since you paid so much money for it and wouldn't be happy with it. I would honestly feel like i was to blame since i have said it works:x ...but it does. I will have more free time this next weekend and i will test more with new screens to let you know how it went.

Meanwhile reduce to two screens max and play around with 15-20 mg max and see how much/how long you need to apply the heat to vapurize it without burning it. I think that and inhale speed is the key. More you do it better the feel for it and what works for you.
