Grinds well and very attractive on the counter. A bit messy as there is no tray to catch over pour.

I’m ignorant about how this compares to other grinders. This is my first step in a bigger espresso journey!
That being said, my gal and I are really happy with the consistency and speed. I’m personally really impressed by how quiet it is. I don’t hear it and our sound travels around our house pretty easily.
No clumps, easy to adRead more about review stating Great for a novice!just. Cannot wait to pair it w/ a Silvia Pro X in the coming year!

Overall, I think I like this grinder – it manages grinds for pour over coffee to the medium roast espressos that I like. It seems to be a little a little challenged at the espresso end – I seem to have to be almost at a calibrated zero to get a 30 S/15 gm in 30 out/ about 30 ml liquid (below the crema). The liquid seems a little short but it tasteRead more about review stating Well Rounded Grinders pretty good – so not sure about that at this point in time. For some reason, I had to disassemble the unit and do a major clean of retained coffee after about 3 weeks of use which is surprising since my beans are not oily. At some point, I’ll add a single dose grinder (probably a P64 when they start shipping) and reserve this for pour over and espresso for guests.

I love this coffee grinder. It was easy to setup and is easy to use. This machine is extremely quite. Running water from my sink is louder than the sound coming from this grinder. Also, this grinder is very quick! I use it to grind coffee for a French press and for espresso. The color is beautiful in our kitchen. This is an awesome machine!
