I was expecting something much more efficient or with multiple blades, but it is not. The grinder is ridicously powerful, but it doesn't really translate as efficient. If you need to tranform your herbs into powder then it is the right grinder, and it is very fast, but a bit noisy. But if you are looking for something that look like hand grinded, this is not the one for you, a regular coffee grinder will gives you similar results.
After a couples of weeks trying to find a way to better use it, I just gave up, and return to my manual Santa Cruz Shredder grinder with it titanium life warranty.
I will keep it for when I need to make my own kief, but not to grind anything I will eat or smoke.
I gave it 3 stars based on: - 1 star for grinding power - 2 stars for the cap that add more protection, and the semi scealed interior (2nd) cap - 3 stars for the price for the power, build, and design
If it was more efficient, with a better control, I would give it 1 more star. If it was possible to auto-grind specific grind and quantity, like my Hamilton-Beach coffee grinder, I would give it its 5th star.
It may still be what you are looking. If you want as much torque and power as possible at a decent price, this is it! :)
