I've only made tincture to date and haven't really had a reason to reduce it to oil, but do you guys really extract with iso or another non-food grade solvent?
I would say this unit isn't the best for those using non-edible solvents. I'ts not a piece of lab equipment. It's not designed for production use.
It's a kitchen appliance. It's designed to do one thing, reduce an extract at low duty cycles. It isn't going to take a solvent down to near zero levels. It isn't designed to run 24x7.
I wouldn't buy one, but that is because of the cost and my lack of need. But if I relied on oils for daily use, I'd certainly consider it. It would save me hours of messy kitchen work on a regular basis. Yes, I still have to make the extract, but that can be done in bulk and put in the freezer.
