I cold brew my coffee. Course grind works best. I could brew 16 oz of coffee at one time but the hopper only holds 12 oz. 
I consider it a bother to grind for 30 seconds and empty the grounds 4 times to get 12 oz let alone refill the hopper and grind & empty a few more times to grind one pound. I have resigned myself to only brew 12 oz at a time but I will have to use use 33% more filters. 
Basically the grinder works ok but I would like to grind a bigger quantity each time.
