What reviewers say about the Opus Conical Burr Grinder
Two whitelisted hands-on testers reviewed this exact grinder: Reviewed (USA Today) and Engadget. Both praise its versatile grind range, genuine ultra-fine espresso capability and batch consistency in a sleek, compact single-dose body. They split on mess and dosing: Reviewed saw excess grounds spill out with no knock knob, yielding inaccurate doses, while Engadget found grounds dropped straight down for a cleaner counter and weighed 70 g in / 70 g out with no retention.

Where reviewers disagree Direct conflict on cleanliness and dosing accuracy: Reviewed repeatedly saw the Opus spill excess grounds with no knock knob, resulting in inaccurate doses, whereas Engadget found grounds dropped straight down keeping the counter cleaner and weighed a clean 70 grams in / 70 grams out with no retention. The two also describe the auto-stop behavior differently.

this is the only Fellow grinder that can grind ultra-fine espresso coffee. And we found that it does so excellently, with a soft texture that even outperforms store-bought Italian brands that we're used to buying ourselves.
It also excels at grounds of all sizes—from fine espresso to medium pour-over to coarse cold brew. And each batch we tested was impressively consistent
there's no knock knob on the side to help remove residual grounds. And as a result, we noticed a large amount of grounds getting spilled out of the machine after grinding was complete, resulting in inaccurate dosages.
grind retention, single-dose (weighed): 70 g in - 70 g out
it's remarkably quiet. I can actually run the Opus at night or early in the morning while my two-year-old is still asleep in a room near the kitchen
When I put in 70 grams of whole beans, I get 70 grams of ground coffee every time. It's been so consistent I no longer feel the need to reweigh grounds to make sure I have enough
Unlike the Ode, the Opus doesn't turn off when it senses all the beans are ground.
