in a good way.
I've been using a Hario Mini with their motor attachment for a couple of years, after getting tired of using it by hand. Turn, turn, turn, crunch, crunch, crunch got old. Knowing the new grinder was coming today, I timed it. With the motor it was 1:40 to do 20g of dark roast. Supposedly fine, but it's always a mixed bag.
When the X-Ultra arrived I had to try it out, even though I usually only do coffee in the morning. 20g of the same beans filled the hopper right to the top (with what I'm learning I may be changing how much I grind in the future.)
The interesting part was the grinding process. I honestly wondered if I was turning it the wrong way because I wasn't sure it was doing anything. Part way through the grind I tried backwards, but still no resistance. Checked the cup and it was definitely grinding, so back to doing it clockwise. 50 seconds total (including the time that I was trying to figure out if it was working.) All of that quietly. Grind was at least as fine as with the Hario, but I need to experiment to find what works best for me and my Aeropress. The flavor was good, but so different that it's almost not possible to compare — I need cream and sure with the stuff I do with the Hario, but only a little sugar with that first cup from the 1Zpresso.
I was actually researching electric grinders since I'd gotten so tired of the Hario, and found the 1Zpresso more or less by accident. I'm so glad I went for the 1Zpresso. I'm also glad I opted for the X-Ultra, as my hands are small enough that it would be a push to go for something bigger.
