Perfect for what I needed.
Color: M01 Black
Love it! If you love fresh ground coffee it’s a must have! We use a Stainless steel k-Cup in our name brand coffee maker. This grinds the exact amount for a K-Cup refill. I think if you were grinding coffee for a full pot it would definitely not be worth the time and effort however for a single cup or a drip coffee maker it works really well! The grind size adjustment is on the main shaft of the grinder so I find it is easy to accidentally change the size of your grinds. Definitely have to be careful not to hold to high up while grinding coffee. It’s easy to use and hold. Looks nice and has held up well. The little coffee catch is glass so it doesn’t stain and is easy to clean. The kids love grinding my coffee for me. They find it fun as well. We took it camping and it was great for coffee around the fire too! Just don’t forget to put the little glass container on before you bring….. it makes a mess.

Small and mighty. Good quality.
Color: M01 Black, Color: M01 Black
In the past few years we’ve started buying only whole bean coffee to use in our French press. Given a few blackouts this past winter we thought it might be a good idea to have a manual coffee grinder on hand (instead of having reserve grounds). This compact grinder is good for a serving of two. It reminds me of a peppercorn mill and will fit 3 tablespoons of coffee beans. Overall I’m pleased with this product and would purchase it again. However, in the future I would also consider a larger and more ergonomic mill as I usually make at least 4 cups (4 tablespoons) of coffee at a time. The top can also be a little tricky to remove. PROS: - Grind setting works well - Quality feeling materials - Relatively simple to operate - Cost/value CONS: - May be too small for some - Top may be challenging to remove (e.g. Those with arthritis or difficulty with fine motor movement)

Compact, Quiet, and Great for an Office Coffee Upgrade
Color: M01 Black, Color: M01 Black
I bought this to use with my AeroPress at work, and for the price, it’s been a solid addition. The ceramic conical burr delivers a noticeably better cup than the pre‑ground coffee in the breakroom, and it grinds two scoops in about 15–20 seconds. It’s quiet, compact, and easy to stash with the rest of my setup. A few things to note: • The body can be slippery, and it occasionally twists in my hand when it catches a bean. A wide rubber band around the body of the grinder fixed that issue however. • Grind consistency is decent, not perfect. After three months I’ve found my sweet spot, but it’s not as uniform as my electric burr grinder at home — which is probably an unfair comparison. Expect small adjustments when switching beans as it can affect bitterness. • I wish it could be taken apart for deeper cleaning; the included brush only reaches the underside of the burrs. Maybe that’s overkill, but I’m used to doing it with my home setup. On the upside, it feels well‑built, works reliably, and the large handle knob is great for anyone with limited grip strength. Overall: A dependable, travel‑friendly grinder that delivers good results for the price. I’m happy with it and would recommend it for office or on‑the‑go brewing.

Satisfying and convenient.
Color: M01 Black
I've been drinking powder coffee and drip coffee, and wanted a change. This thing is really satisfying to use (I love the crunch) and clean. It's really sturdy, I've dropped mine once or twice and it's still going. It's small, and easy to adjust, but I mostly just grind it medium. It's utilitarian, but still looks quite pretty. Looks just like the pictures.

I use it everyday and love it
Color: M01 Black
I was worried when I first purchased my mini manual coffee grinder. I was afraid I would not be able to use it due to arthritis in my hands. Well! No worries now. This little guys works great. It grinds fine to course and without undies stress on my hands. Thank you for making such a great grinder for all us nomad folks who enjoy freshly ground coffee in our rigs.
