The thing about these kinds of vaporizers is you have to find the sweet spot. It can take some time. Personally, I don't like the digital displays. What exactly is it measuring? The air going past the element? The element? It's not measuring the herb in the wand...just seems a bit too complicated.

I have a Silver Surfer and I keep it turned to about 2/3's of the way. I'll play with it depending on what's in the wand. Just play with it a little, you'll find the sweet spot.
