Opus’s burrs sure are burrly, but, after a long time, even the burrliest burrs need to reset. This includes only the inner burr. If you’re looking to replace the entire burr set, you will also need to purchase the Outer Burr.

Ellie P. ★★★★★

Took me a while to figure out exactly which burr I needed, but this inner burr dropped right in and the grind consistency improved noticeably. It feels sturdier than the original, and my morning pour-overs are much more even now.

Joseph Y. ★★★★★

Finally got around to swapping out the inner burr after months of daily use, and it fit perfectly with no wobble. The grinding consistency is noticeably more uniform now, especially for my morning pour-over. Definitely worth the wait to restore the old grinder’s performance.

Olivia ★★★★★

I was worried about finding the right replacement part, but this inner burr lined up perfectly with the old one. It took me maybe ten minutes to swap out and the grinder’s back to its consistent, fine grind again.

Matthew R. ★★★★★

The inner burr dropped right into my grinder without any fiddling, and the grind consistency is noticeably more uniform now. Feels like I've got a new machine for half the price.

Mia ★★★★★

I was worried about getting the alignment right, but swapping this inner burr in took less than five minutes and the grind consistency is noticeably better than before. It feels solidly made and the coffee tastes cleaner now.

Jacob ★★★★★

My old burrs weren't grinding evenly anymore, but swapping in this inner burr was surprisingly easy and now my morning coffee tastes much more balanced. Definitely worth the upgrade if you've been using your grinder for over a year.

Madison ★★★★★

Installed this inner burr in about 10 minutes and my pour-overs are tasting noticeably cleaner—no more fines clogging the filter. Exactly what my setup needed after a year of daily use.

Brian G. ★★★★★

Finally found a direct replacement for the inner burr without buying a whole new set. The fit was exact, and my grinds are already more consistent now. Such a relief to just swap out the worn part instead of the entire assembly.

Ruby ★★★★☆

Fits perfectly with the existing assembly, and the grind consistency is noticeably better than my old one. Would have liked a bit more guidance on the initial calibration, but otherwise a solid replacement part.

Olivia ★★★★☆

I was worried about compatibility, but this inner burr fit my grinder perfectly. The machining feels precise, and it's noticeably quieter during operation than my old one. Only giving 4 stars because I wish the packaging had a simple instruction sheet.
