KONA Manual Coffee Grinder, Conical Burr Mill with Adjustable Setting, Best Ceramic Burr Coffee Grinder for Aeropress, Drip Coffee, Espresso, French Press, Turkish Brew

I was a bit hesitant about ordering this grinder. The reviews that mentioned "5 minute" grind times were my biggest concern. Since I am only going to use it for French Press I decided to take a leap of faith and I am glad that I did.My previous grinder was the Cuisinart DBM-8. It was fast but there were a lot of fines in the ground coffee. That translated into sludge at the bottom of my cup. This grinder cut the fines by about 80%. There are a few but overall the grind in much more consistent.I set the burr adjustment nut so that it is even with the threaded shaft that it travels on. (See first picture.) That gives me a nice course grind for the French Press. I fill the hopper to the top of the four vanes and find it to be perfect for a 12 oz. / .35 liter Bodum Press. (See second picture.) My first time using the grinder took 1 minute and 35 seconds to complete. After several uses that time is now below 1 minute. I find it best to hold the grinder in my left hand and turn the handle with my right. I found that holding the bottom of the grinder on the counter was "counter productive". It takes approximately 75-80 revolutions of the handle to grind the aforementioned amount of beans. The unit is easy to disassemble and reassemble. There is minimal static cling unlike the Cuisinart with its plastic hopper. Which takes me to the last part of this review. Several people complained about the glass jar. It is a thick glass and unlikely to break unless you abuse it. My thought is that if you are so afraid you might break glass, it may be safer to pay someone else to make your coffee for you. Bottom line is this... I would buy this for a friend, I would buy it again if I "break it". It is a great tool for a fair price. everyone may not agree with me but I think it is a great value.2 years and I still use it every day. It still hasn’t “broken” and it still grinds my coffee. I still love this thing!

I bought this to use to grind my coffee for my K cup refillable unit. It does a good job, I gave one star off for the following reasons. 1. It's not totally consistent grind. Not too bad but there is that. 2. I find it awkward to screw the unit together. When doing that, generally I use the "reverse thread" trick to stop it from cross threading. This unit doesn't seem to like that trick and you have to be careful NOT to cross thread so I fumble a bit with it. 3. I wasted my time trying to use the coupon that came with the grinder for 2 oz sample pack of coffee. All I got was a "404 page not found". I searched and apparently the coffee they had is sold out. Well, before you ship the grinder, take the darn coupon out of the box, then nobody is flailing around trying to find something that doesn't exist. 4. I wish the neck of the glass jar was just a LITTLE bigger around so that when I fill the K cup I could store a couple of them in the jar. Makes me wonder though, is it airtight? I generally keep two in a Tightvac overnight.I got another hand grinder to compare and it's similar to the number 1 seller on Amazon. Silver looking - tube like grinder. The grind is very similar to this one, the burrs look identical. I'm sure that every grinder out there in this category uses the same. It was $7.49. When I was comparing, most every hand grinder had very good reviews.I chose this one for ease of use and only having to fill in once to get the two Kcups of coffee. Would recommend. BTW, I ground up Koffee Kult Dark Roast Coffee Beans and my wife said it was the best cup of coffee of any of the Kcups I've tried (Just got the Keurig at Christmas.)

I've tried two other manual coffee grinders in this price range and I had issues with both of them. The first was a hopper/jar burr grinder with an open top that would catch while grinding (causing beans to go flying everywhere) and it would often come unscrewed during use. The second was a metal cylindrical-style burr grinder that would also come apart during use since it didn't even screw together, and to make matters worse that grinder wouldn't ever produce an even grind.I haven't had any of the above problems with the KONA manual grinder. It's reasonably comfortable to hold in your hand while grinding and it doesn't come apart during use. The plastic lid stays put on top so I haven't spilled any beans while grinding them. It grinds the beans evenly and I haven't had any issues with an inconsistent grind so far.One of the biggest problems I have with these cheap burr grinders is that it can be difficult to know how fine the grind is set before you actually start grinding. Like the others, the KONA grinder doesn't have indicators on the dial to fix that issue. However, since the KONA has a clear bottom, you can try grinding a few beans at a time to inspect the grounds and make sure that the grind level is where you want it before you begin grinding a whole batch of beans.Since this is a fully manual grinder, it will take some time to grind your beans. I grind two tablespoons or so at a medium-fine grind and I've found this takes me less than a minute to accomplish. It's really not a big deal but it is something to be aware of if you really have to have your coffee ASAP. If that's the case, you'll probably want to look for an electric model.In all, this is a good grinder available for a reasonable price. I recommend it to anyone who wants to try a burr grinder but doesn't want to spend a fortune on one.
