Fellow Opus
Reddit take
AI summary of the Reddit excerpts below — not a quote
The Fellow Opus is widely regarded as a high-value, versatile grinder that performs well for both espresso and filter coffee, though it is polarizing due to its interface. While users praise its aesthetics and 'bang for the buck'—especially at sale prices—the dual-ring adjustment system is frequently described as cumbersome and unintuitive. Opinions on retention are mixed; some find it a major drawback, while others consider it manageable with specific techniques like pumping the lid.
Pros
- Excellent value for the price, particularly for entry-level espresso
- Versatile performance across brew methods from espresso to filter
- Aesthetic design that is more compact and modern than many competitors
- Durable plastic construction that does not feel cheap
Cons
- Cumbersome and unintuitive dual-ring adjustment system
- Significant retention issues reported by many users
- Micro-adjustments are difficult to perform physically and understand without documentation
- Static and mess can be an issue with the stock catch cup
Caveats
- Many users rely on the 'Beanie' app to calculate the math for the dual-ring adjustment system
- Retention can be mitigated (down to ~0.2g) by pumping the lid while the motor is running
- Some users recommend swapping the stock cup for the metal Fellow Ode cup to reduce static
- Advanced users sometimes mod the grinder to be stepless to bypass the difficult adjustment rings
Best for
- Budget-conscious users wanting one electric grinder for multiple brew styles
- Beginner espresso enthusiasts who value aesthetics
- Users who don't mind using an app to help dial in their grind
Avoid if
- You want a simple, single-dial adjustment interface
- You are highly sensitive to grind retention and static mess
- You prefer a workflow that doesn't require 'workarounds' like lid-pumping or third-party apps

What redditors said (10 of 34)
it’s a more than serviceable grinder and fantastic bang for buck in my opinion. Especially if you do anything filter. ... all that being said, I think it is well worth the Black Friday price and a rather aesthetic grinder
The biggest cons are the following: 1) retention. ... 2) grind size adjustment. This is the bigger issues. I have no idea why the designer decided to use a dual-ring combination system. It’s quite cumbersome. I find it very difficult to turn the inner ring just a single click in any direction. Always wants to go 2 clicks. The beanie app is really helpful in terms of doing the math for you, but physically adjusting two rings, one of which is hard to adjust, is pretty annoying.
If that is the fellow opus, it is a pain for retention and not forgiving if your beans don’t happen to work with that setting. Even the micro is too big a step to dial in
Should have gotten a better grinder and a worse machine. Nice machine though, but that grinder is gonna be ROUGH
you could upgrade the opus grinder in the future but the opus2 is apparently much improved from the first.
This grinder should be good enough if you drink medium to dark roasts & milk drinks primarily. If you end up experimenting with lighter roasts in the future, you might consider a grinder upgrade.
And interesting grinder to machine ratio - endgame machine and sub-beginner grinder. I’d get a better grinder next
Setting 7.75 on a Fellow Opus.
I used to have close to 1g of retention with the Fallow Opus 1.
The fellow opus seems to have issues with retention
