1Zpresso J Manual Grinder, Aluminum

Very mixed feelings on this. Not sure I'll keep it. It is well made. The Amazon reviews were very misleading though. Top review says only 5 seconds and a few turns to grind your beans. Others say 15 turns, or 30 turns, and 30-60 seconds. That might be true for a tiny amount of beans at coarse grind. But for 20g of beans (2 scoops / standard coffee amount for me) at Aeropress or drip settings, it takes 50 - 55 turns or about 30-60 seconds depending on how fast you are. At espresso fineness, it takes 60-80 turns. The product marketing is misleading - it says it fits 30-35g of beans, but that's only the grounds container. The top part can only fit 20g. The fact that the grounds container is a bit oversized doesn't save any time, because I need to grind 40g of beans to make 2 cups. (I know some people use 15g/cup, but that's not our taste - also, note I'm making 10-12oz cups, not the "standard" coffee maker cup of 6 or 8oz). Since we have two people that drink coffee, we always have to do 2 rounds of this - fill with beans, 50-55 cranks of grinder, pour grinds into coffee maker. This is fine if you're single or this isn't your only grinder. But I was looking for a standalone grinder, not a collection of grinders. And if friends or family come over we might need 4 cups. Now we're at 200 turns of the grinder! If we need 4 cups twice per day, that's 400 turns. Great for getting strong forearms, but it gets tedious and boring fast. You can use an electric drill or screwdriver but it'll need to be a dedicated (clean) tool or you'll get metal shavings and wood shavings from your other household projects into your coffee beans. At that point I'd rather just buy an electric grinder. They ship no setup instructions or manual - we live in QR code manuals world now - okay no problem as long as it goes to a good manual. It does not. The manual is confusing and incomplete, it doesn't tell you what to adjust the grind to, you have to look that up separately in a blog post on their website. Also that blog post is outdated (2020) and has calibration tables only for the Jx and Je grinders which are obsolete / discontinued model names. You have to somehow know the J grinder you bought is equivalent to the Jx (but not to the Je, which will give you incorrect settings). Overall it's a well made manual grinder that is poorly documented, and mis-represented in reviews as being quicker than it is, but still a great solution if you are grinding small amounts of coffee.
