Our community has rated this post as helpful. If you agree, why not thank

Probably junk. Spend a little more and get the Kingrinder P0 for $30. Best budget grinder if you're not doing espresso.

That's when you chew the beans. I don't know how humanity invented something that requires so much effort for so little result.I do appreciate a fresh ground cup of jo, but when you accept a 2nd cup from your friend and then watch 3 minutes of grinding you start to feel bad.
I went to Costa Rica and saw the whole process. If you think grinding coffee is a long process, you should see how much else goes into it.

Here's a great video I took from my El Toledo coffee tour. I was able to cut it down to only 39 minutes. I have a few hours of video.

Those interested in the process will enjoy this. And this is my video on coffee roasting. The darker the coffee, the less caffeine and natural flavor comes from the coffee. You're getting a burned flavor, which is more consistent, so more people prefer it.

When I saw "Circle Joy" in the name, I thought it was a different kind of pump.

Ceramic burrs. Bestseller list has a bunch of these no name $20 or less manual grinders with similar features. Do any of these actually perform decently?
I have the KINGrinder P0 and it has a stainless steel burr. Been going strong for 9 months and it reviews well. Looks like they increased the price to $30, but still a good deal.

Just got mine. It is trash. The burrs rub together and creates powder that you will end up ingesting.

These work actually pretty well for drip or cold brew. They wont grind enough for espresso.

Very common on these cheaper ones and often a point of failure. I knew this from reading reviews on 10+ different brands...but still bought one(not this specific one but looks just like it and same price point). Sure enough, that plastic piece broke in about two weeks.

I'd love to get a more robust (more metal parts) one but just can't justify the cost for how much I'd use it.

Thanks for this. I want a grinder but use pour over makers and was considering this. I'd like to get a manual grinder that does coarse grinds well.

Quote from MrBeauxjangles View quoted comment :
I used to grind my own beans and this looks like fun for camping and such, but I tried Nespresso at a friend's and it was a game changer. Melozzio and Double Espresso for the win. A little on the expensive side sure, but that first cup of coffee each day is something to look forward to so it ought to get worthwhile attention. I'd be more inclined to buy a power source that could run my Nespresso on a camping trip than go back to grinding. I may have a problem.
Nespresso is okayish but you'll get something much better if you grind and brew yourself. And better for the environment and less good for nestle

Quote from Justin09 View quoted comment :

Serious question, but how long does it take to hand grind enough for a full 12cup pot? I am not that big of a coffee nerd and I like my conical burr grinder but my best guess answer to that question is definitely a blocker for me (and it may not even be relevant for a lot of coffee nerds but I just like the convenience of drip and to get things moving in the morning because I hate the mornings haha)
3-4min. Use a kinggrinder with a drill
