I own 3 grinders, a cheapo off Etsy that's inefficient and gets gunked up quickly, a BCG and. Flower Mill.
To my own surprise, I end up using the Flower Mill the most. I bought it because I was skeptical.
I'm gonna be honest. The feeling you get from the Flower Mill when the magnet gentle pulls the flower in as you roll it around os EXTREMELY satisfying. Endorphin rush.
BCG is a champ obviously and can cut through anything, but it's ripping your herb vs rolling.
I haven't don't any bro science experiments to see while smokes better. I imagine with less of a fine grind I'm missing out on a little, but it is worth it.
Thanks for the information. The BCG is probably going to start getting more use.
