Cuprajake I thought it was wholesale nonsense to be truthful. When you review something, you either ramble like he did, or you decide upon the point you wish to put over and base your review around that. For example
The Niche Duo allows you to make good espresso or good filter brews by swapping two specialised burr sets in one grinder. The Mazzer burrs have been specifically selected for their high engineering standards of uniformity and to help keep the cost down. Yes, for some folks who do not drink brewed coffee, then the purchase is pointless….or is it. For the price of the Dup, what other 83mm burr grinders are there? Is it fair to compare the DF83. Do we know the non-subsidised price yet? Do we know for certain, what burrs they will use? In other words we are comparing a known quantity to an unknown but with time, all these questions will be answered.
Instead, his review opened the door to all the Niche knockers to pile in and have a go. At the end of the day, all this is just his opinion and not fact. The next red bus to come along might be completely different. I would have been more impressed if he had read the manual which tells you under no circumstances do you spray the beans with water, yet he recommends this.
Horses for courses but for me, the first two reviewers (him and Hoon) have both been 3.5 out of 10
