So far after trying the oil and the mushroom setting, I can say the device works. Everything is ground and cooked nicely in the device, and the final product was stronger than anything I ever tried to make. I still need to try it with butter and Glycerin, but so far so good.
Keep in mind as well, that I used well vaped duff only, and still ended up with a nice strong olive oil, with very little effort on my part. Pretty impressive for a lazy guy like me.
The unit itself is pretty solid with most of it being stainless steel. I would like to know more about how impact resistant the plastic parts are, though. And yes, I agree...a sealed lid would be ideal.
