Looks you have brought a touch of Dyson to the world of coffee. I hope you do well! I can't see your presence online at all, like no search results other than this HN post which is odd. If you can ship in January you might want to be marketing a bit more.

Have you patented the cylindrical grinder? That looks like a new idea. I wouldn't mind trying that.

Needs a youtube demo video I think. Plus you might want to give one to a few coffee influencers. Maybe give it to a few r/espresso regulars first to pedant about, then fix those things, as you don't want a crap review.

Or can some RSU rich HN-ian just buy it and post a review, pls :-)
