1Zpresso J Manual Coffee Bean Grinder with Adjustable Settings Patented Conical Burr Grinder for Coffee Beans & Aeropress Drip Coffee Espresso French Press 35 g Bundled with HogoR Instruction Manual.

I got tired of having to throw away electric grinders because some sensors stupidly decide to not let the engine do its job of crushing the beans. I also got tired of spending 2 minutes grinding with one of those travel portable grinder. This one on delivers exactly what I needed. It takes less than 30 seconds to grind enough for a double+ espresso (I use about 20 grams) and it produces a powder as fine as you'll ever need (I had to work up the settings to get to something my machine could work with). It feels really well built and hopefully will be durable. It better considering it is far from cheap.

The media could not be loaded.  Yo lo compararía con el comandante, una molienda super homogénea, y rapidez en la molienda, en el video muelo 15 gramos de café en solo 19 segundos. Fácil de limpiar y bonito. Un poco pesado por sus materiales pero eso sí, muy resistente y robusto.

I have a sad little high RPM electric grinder that just works is as best I can say. I don't have a budget at the moment for a proper electric grinder so I figured why not a manual one. I have to admit this thing is very nice. To look at and to use. It improved my draw down with my V60 brew so, for now I am happy.

Nice hand-mill for coffee beans. Quick and light grinding. Z1presso JX is more comfortable than Timemore G1.

Los materiales son de exceñente calidad, moliendas precisas, varios ajustes y molienda rápida. Muy recomendable para métodos de extracción por goteo, aunque si logra llegar a moliendas para expresso. Recomendable sobre todo por su relación precio calidad

The manual coffee grinder is easy to use and is efficient. It grinds the coffee beans as chosen on the scale and makes for a tasty cup of coffee.
