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.

Good for the price, but has its limits
Color: M01 Black
You get what you pay for. Grind consistency is decent, but even the lowest grain setting won't get you close to a true espresso grind — it still produces a coarser result than expected. It's fine if you're using a pressurized portafilter, but not ideal for a bottomless one. Worth considering only if you don't mind spending 15 minutes a day grinding your morning coffee. After a few months, I got tired of the manual process and now just buy pre-ground espresso from a local coffee roastery

Strong, smooth, and reliable☕️
Flavor Name: Major Dickason's Blend, Size: 10.5 Ounce (Pack of 1)
This is iur go-to dark roast. It’s bold without tasting burnt, and the flavor is really smooth. Wakes you up without any weird aftertaste. I’ve had it a bunch of times and it’s always consistent. Solid cup of coffee.
