Two important things about me - I hate picking stems out of flower and I like a very fine grind. I previously would turn my grinder upside down while grinding to hit the correct grind. With the Flower Mill and their #1 plate both of my annoyances are gone. Stems caught above the milling plate and the #1 is the perfect grind for me.
I am going to guess they don't want a picture of flower in their reviews but rest assured, if you like a fine grind the #1 plate is perfect.
