Rated 4 out of 5 by from Christmas Gift I gave this to my boyfriend as a xmas gift and we have been using it frequently for past 3 and a half months. It works great and is easy to use, especially with darker roasts. I have small hands and it is small enough to hold. I might add a few broccoli rubber bands to improve grip. Two batches are enough to make a standard Press pot worth of coffee. Handle comes off easily for storage which means it can come off while attempting to get lid off but after a short kinesthetic learning curve this is not a problem. Lid fits very tightly so it took me a few tries to get open first time. We didn't adjust grind as it arrived with, for us, perfect grind.

Rated 5 out of 5 by from There was an issue with the Hex shaft We did have an issue with our production of the Java Mills that has since been corrected. All current stock have the correct hex shaft and anyone that happened to get a defective one can call customer service at 800-704-4474 and they will provide a replacement hex shaft to rectify the problem.

Rated 5 out of 5 by from FREAKIN' AMAZING GRINDER I've owned [and used] this grinder for about two (2) years. Pretty much 6 out of 7 days of the week and sometimes twice. It has been with me throughout my travels aboard my merchant vessels and word has spread on how well this has been. If you take off the bottom cup of the grinder and leave at home, it's not only extra weight that's gone, but you'll also be able to fit it nicely in the GSI travel french press (which I've owned the same amount of time!). Be sure to have some beans at the ready in the grinder! Haven't even thought of getting a "standby" extra, just in case it breaks, but it won't, unless you put a bean that is not intended for a grinder.

Rated 5 out of 5 by from Excellent design for a simple task I bought this as a compact grinder for at home and occasionally on the road. I normally take tea out backpacking but I can keep this in my car and if I'm on a long road trip or staying the night somewhere else I can run into a gas station for hot water and crank out some coffee grinds in a minute for my travel french press mug. Haven't had it too long yet but it has solid construction and a simple mechanism that seems to work well. The handle is genius as it stores almost flat alongside the body. Its a little annoying have to take the top off to add beans but you can use it to store 2 cups worth and just throw it in your bag which is nice. The bottom cup is a good size too for pouring into my aeropress. It's a shame they couldn't design it 2mm narrower to fit inside it!

Rated 5 out of 5 by from Solid, Small, Reliable. I purchased this after accidentally buying some coffee beans instead of preground coffee. I had never ground my own coffee before. Now, I use this every single morning at home and on the trail. It claims the option to grind fine or course, but I only use the fine option for my AeroPress coffee maker. I have had zero issues with it, and it is as strong now as it was a month ago when I bought it. And again, I use it every single morning.

Rated 5 out of 5 by from Great for the cruising sailor This is a dependable, compact gadget for the perfect cup of coffee away from the grid. It may take a little practice to find the correct grind for your portable coffeemaker, but it is worth the effort. So far, with just reasonable care, it appears to be rugged enough for our use.

Rated 1 out of 5 by from Poor build quality. I have had two of these in one month. The first one i had purchased, the hex shaft sheared off and dropped the grinder into the hopper. The second one i purchased, broke when i put the lid back onto the grinder. There is a rather large crack next to one of the braces running down to the ceramic parts. Hopefully this third one will last, if it doesn't i guess i'll just purchase a Hario hand mill.

Rated 3 out of 5 by from I loved it until it broke I have had this little guy for a month or so and used it nearly everyday right up until the hex shaft sheared off. The grinder, spring, and grind adjustment are now partying in the hopper. I am bummed, I really dug this grinder, it was nice and compact and made a consistent grind. Taking it back it REI.

What is the proper way to clean/maintenance this product? Do you simply rinse it with water? Wipe only? 

Asked by: joontheton
Please disregard REI advice to use soap. The burrs are ceramic. Should they absorb any of the soap (they will) you will have a very tough time getting the taste out. Rinse with hot water and allow to fully dry and you will be good to go.

How much grams of coffee powder when the bottom is full??

Asked by: alfred
The Java Mill can be set for different grinds, from fine to coarse. When set for a coarse grind, the storage chamber will hold about 25 grams (just under an ounce) of ground coffee.
