I've had this for 9 months now. I've used it every day without fail for approximately 60g per day. I use espresso (Gaggia Classic), V60, Aeropress, French Press, Moka Pot and cold brew. This is spot on for all of these. For espresso, it takes about 60 seconds to grind abou 18g of beans. For French Press, it takes about 15 seconds for 15g of beans. I've never used a faster hand grinder.
