JammyDodger I’d be very interested to hear your thoughts on the matter
I have both the Niche Zero and the Duo, although I call mine Uno as I don’t drink filter coffee - so the whole concept swapping burrs for me is a moot point.
Despite having owned conical and flat burr grinders in the past, for years I kept reading that flat burrs are better than conicals and vice versa. So, when the Uno launched (read: Niche started selling the grinders with only one burr set) I went ahead and bought one.
Hen you may ask - why? Why didn’t I buy a df64, or a Lagon P64, or a Monolith? Simple: for the last two, price. It’s just a little bit more than what I would want to pay for a coffee grinder I used twice daily. For the df64, I read good and not so good things about it, and, at least at the time, the only option was to modify the grinder so it works well.
So, for me, the Uno was the right grinder as I wasn’t interested in swapping burrs (SSP this, SSP that, bla bla bla). I just wanted to grind coffee with a flat burr grinder without having to puff air through the chamber (bellows), removing chute screens, “hot starting” etc, etc. I wanted to put coffee beans in, turn he grinder on and grind away. For me, the Duo gives me exactly that, and I knew that, unlike other grinders, it’s been tested for a couple of years before being rolled out from the production line.
So yeah… boring. But it works, and it works well, for me at least. 😊👍
Have I had problems? Not yet. Could I potentially save myself half of the cost and have the same result in the cup with another flat burr grinder, 64mm or anything else? Probably.
