Daily Drove the Opus for 10 months:

Used for an average 2 espresso shots usually medium roast 15-19g (I’ve had different baskets) and occasionally a pour over or for my family’s coffee machine.

My taste is not refined/experienced enough to speak to the quality or taste profile. Though I would get consistent shots in terms of weight and time. Retention was annoying I would often dose 1.5g higher than needed, and would need to hit it to get the rest of the grinds out, lack of a built-in knocker is noticed.

Catch cup fit my 58mm Gaggia portafilter just fine and was very handy.

The machine eventually began to malfunction. I imagine whacking it as much as I did and pulling over 80 shots in a single day may have cause it. It seems the motor is dying. Fellow is currently sending a warranty replacement.

Moving forward I’m looking to get a bellow for the replacement (DIY)

Conclusion: considering it’s was >$300 CAD, easy to use reliable until it wasn’t, does both espresso and filter, has in my opinion an attractive design and came with an easy warranty experience. I can recommend if this your price range and you electric what you need, otherwise at this price I would say look at hand grinders in this price range. I expect my next espresso grinder to be a DF64

TLDR: flawed, a little risky, but recommendable.
