I've heat pressed my own weed a few times with much lower cost heat presses and have had varying success with it. Some mediocre, some some of the best dabs I've had lol. But that's pressing flower, not hash even
Also yeah dry herb vapes are the shit. I have a bunch and finally settled on what I'm happiest with, vape wise, until I discovered weed is causing all of my gut problems and I need to not smoke/vape anymore lmfao
