It's proven that your beans lose all the amazing good-for-you nutrients and freshness within the first ten days of roasting... and on darker roasts you shouldn't exceed 7 days

(I knew this when I bought it) and is messy (grinds all over the table) but jams constantly with dark roast and occasionally even with light roast

The oils on dark roast coffee, even, occasionally the random arrangement of the beans in light roast coffee, cause the beans to jam in the feed ramp

I know the roast profiles I prefer

Dark roast (French, 2nd crack+) beans tend to stick and jam, due ironically to the short hopper design Fellow claims as an improvement.

The second problem is that it has trouble with every dark roast coffee I put into it.

But this almost always happens for dark roast.

Bought early as I like their design, but moving parts just aren't their thing.- cannot handle finer grind settings (no espresso nor aeropress)- a ton of retention (grounds stuck in machine)- big mess everywhere due to excess static & flawed bin design- hopper can barely hold 70g of beans- dark roasts will not work at all!!!!!

n’t grind fine enough for them, I use a chemex and Blue Bottle dripper pour over and have no problems with the grind size
