Sf Giant, what do you recommend? I have an omicron sitting around collecting dust, a thermovape revolution collecting dust and now I don't have much of a reason to drop a couple hundred on the Persei, especially because I hate those cartridges. MH88: just a few things i'm sure you already know. It took me a little while til I got the correct temp I wanted to vape bud at in the raw, I've heard some people grind it like a volcano when putting in the raw, and i've also seen people put small pieces bud, see whats best for you. That combined with a screen or screens with the correct button timing should equal good vaporization. It may take awhile, but im sure you will be able to do it, once you get familiar you will love this device.
