The catch
Fellow Opus 2 Conical Burr Grinder
For espresso, grounds go through a catch cup and get transferred, instead of using Breville's supplied cradle.
Side by side
Fellow Opus 2 vs Breville Smart Grinder Pro: Opus stands 4.8 inches shorter, Breville includes direct-fill cradles
Quick verdict

Before you buy
Why, and what it costs you
Opus is shorter by 31.4%
With a twelve-inch limit on body height, Opus fits and Breville does not. You still need to check working clearance.
Where this comes from
(15.3 - 10.5) / 15.3 × 100 = 31.4%. 10.5 sits under twelve and 15.3 sits over it. Those figures are body heights. They do not cover the full space needed for filling.
The catch
Breville Smart Grinder Pro
The 15.3-inch body takes 4.8 inches more height.

In practice
Differences you will notice
Opus is shorter by 31.4%
With a twelve-inch limit on body height, Opus fits and Breville does not. You still need to check working clearance.
How we worked this out
(15.3 - 10.5) / 15.3 × 100 = 31.4%. 10.5 sits under twelve and 15.3 sits over it. Those figures are body heights. They do not cover the full space needed for filling.
Neither grinder is ruled in or out by a 54 mm basket
Each comes with equipment for that basket size. What you are really deciding is whether to transfer grounds from a catch cup or grind with the portafilter sitting in a cradle.
How we worked this out
Fellow specifies an espresso catch for 54/58 mm. Breville supplies a 50-54 mm cradle plus a separate 58 mm cradle.
There is room in the Opus catch for one measured espresso dose
An 18 g nominal dose is 12 g under the espresso catch's stated 30 g capacity. That headroom does not make the grinder an automatic weight doser.
How we worked this out
30 - 18 = 12 g. Opus stops automatically, yet you still decide how much mass goes in. Breville's timer does not measure the grams delivered either.

Spec by spec
Where they really differ
| Spec | Fellow Opus 2 Conical Burr Grinder | Breville Smart Grinder Pro | In practice |
|---|---|---|---|
| Published body height | 10.5 inches | 15.3 inches | Opus is lower, but taking off the lid and filling it still takes extra room. |
| Adjustment method | Stepless side dial | 60 positions | How each grinder is controlled differs, and that proves nothing about grind quality. |
| Dose workflow | 100 g single-dose load bin with automatic stop | Programmable timer in 0.2-second steps | Opus is built around loading a measured dose, whereas Breville centers on delivering by time. |
| Espresso transfer equipment | 30 g catch compatible with 54 mm and 58 mm portafilters | Direct-grinding 50-54 mm and 58 mm cradles | Common espresso sizes work with both, though the handling steps differ. |
| Brew-method scope | Espresso through coarse brewing | Espresso through French press | Switching brew methods does not by itself call for a separate filter-only grinder with either model. |
Trade-offs
What each pick costs you
With Fellow Opus 2 Conical Burr Grinder

Decision guide
How to decide
Opus 2 is the pick for a shorter single-dose grinder with stepless adjustment and automatic stopping. Smart Grinder Pro is the pick for timed cup or shot selection and included direct-portafilter cradles. The published body heights make Opus 4.8 inches shorter.
Check shelf clearance before deciding on a workflow
A 4.8-inch height gap can settle things fast at a cramped coffee station. Fitting below a shelf is only the first check. Leave room to remove the lid and pour beans safely, or plan to slide the grinder forward. The published body height is no stand-in for the access you need every day.
Decide where the grounds should land
Grounds go into a magnetic catch on the Opus, and an espresso catch is included for transfer. Breville provides portafilter cradles for direct grinding. Neither arrangement is universally cleaner or better. In practice, you are choosing between an extra transfer step and a basket supported beneath the grinder.
Plan to keep the scale
On the Opus, automatic stop ends the single-dose run, while Breville stops after the programmed time. Neither measures the grounds in grams. Weigh the beans before loading the Opus, and verify the result when precision matters. With Breville, check the timed output again whenever the coffee or grind setting changes.
What this page can’t tell you
