tompoland If so then yes indeed, the shape is cartainly similar. Both 38mm burrs too. Did the above grind well for espresso or was it mainly for filter? Certainly less expensive, by a long shot.
It could grind for espresso, but I felt too too long, filter was fine, just press the button and leave it to do it’s thing. The reason it wasn’t sold as an espresso grinder was because I felt the grind time was excessive. Funnily enough, before the burr change to coated burrs and clearly a geometry change for some reason, the espresso grind time was around 90s on the prototype and filter was much faster as well. When the production ones appeared, it was slower. I could grind 360g+ of filter coffee on one charge though!
Using the handle was just not worth it as pressing the button was much easier and the way pieces stacked inside each other was great for travel.
Of course, if you are prepared to hand crank and pay a bit more, the 1Zpresso used to be great. I remember being impressed when I first came across them 4 years ago, a bit before the influencers. I have a JX pro, which grinds for espresso in 30 seconds the unedited vid. Not as portable as the electric powered one though.
