Got my bags ground to the exact pour-over setting I asked for and they arrived perfectly uniform, not a single boulder in sight. Saves me from buying a grinder, and the coffee tastes as fresh as whole bean since it was ground right before shipping.
The fee structure is so transparent it actually makes me feel less stressed about every transaction. I’ve saved a noticeable chunk this month just by knowing exactly when and what I’m paying.
The grind consistency options are clear enough when you're checking out, but the fee itself feels a bit steep for what's essentially just running beans through a machine. It's convenient if you're stuck without a grinder, though I'd probably skip it next time and buy whole beans instead.
