Fellow Opus
A popular design-forward electric burr grinder that looks premium but runs beans and grounds entirely through plastic - plastic hopper, plastic catch cups, plastic body. Documented so you can tell the styling from the materials.
The verdict: Minimal plastic contact
The burrs are 48mm stainless steel, but essentially everything else in the coffee path is plastic. Fellow's own materials list is "high-quality ABS, PC, nylon, and POM plastics, stainless steel conical burrs, and wood accents." The bean hopper is plastic, the two magnetic catch cups (standard and espresso) are plastic, and the exit chute the grounds pass through is plastic. Grounds fall through plastic into a plastic cup - which is why the Opus builds in an ionizer to fight static. It's BPA-free and nicely made, but it is not a plastic-free grinder; the metal is basically just the burrs.

An electric conical burr grinder built around Fellow's design-first styling: a clean matte body, a single-dial grind adjustment with 41 settings from espresso to French press, and a built-in anti-static ionizer. Beans load into the top hopper and grind into one of two magnetic catch cups (a standard cup and a smaller espresso dosing cup). It's a frequent pick in "nice coffee setup" guides and is quiet, well-reviewed, and BPA-free.
Pros
- Stainless steel burrs; good, consistent grind for the price
- Well-designed, quiet, single-dial adjustment; anti-static ionizer
- BPA-free plastics
Cons
- Plastic hopper, chute, and catch cups - beans and grounds travel through plastic
- Premium price for a plastic-bodied grinder
