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.
It's my only grinder. It's good quality, grinds perfectly and easy to use and clean.
Great hand held grinder. Very sturdy and well constructed so it will last a lifetime (not lightweight!). The instructions suggest using a 'vortex' technique when grinding (looks a bit like doing a sideways doggy paddle). It definitely works and you grind beans quicker. I would also suggest that you look at youtube videos for how best to set the grind from fine to course. It takes a little practice to figure out how to refine the setting. Now i've set mine to just right for my espresso machine I rarely touch the setting. I weigh beans before putting into the grinder rather than after grinding (it is a lot easier).
Great quality by OE. I could happily live with this as my only grinder.
