i have the Deva for 13 months now and no problems whatsoever.
i do not worry at all about the extra activation. It's not that the grinder is used a lot a day during private use.
The motor should be fine with that, and as you press the button anyways to stop grinding, it is very quick to do one extra.

I'd say no. Tapping on the funnel or banging on the top don't make any difference. Def need a couple of pulses at the end of the motor. I often hear a last bean or 2 go through the burrs as well at this time.

A couple days ago I reached out to Kopi and they were super fast addressing some of my additional questions and they went into a lot of detail on each. They've reiterated and confirmed much of what has been said here.

I have been debating between the p64 and waiting for the Zerno when I found out about this grinder. There were some things I didn't like about the p64 (some minor aesthetic things along with the very high price), and just a lot of unknowns with the Zerno (lots of changes being made to the design and unknown delivery dates). The DEVA is very compelling for its price point!

I guess the last thing to decide is whether to go with the stock Super Jolly's or the SSP High Uniformity (only an espresso drinker here)...

Thank you everyone for your help - it has been so useful.

Hi there,

anyone with experience with the multiporpose, high uniformity or ssp cast burrs installed on the kopi deva?

i want to extract more clarity on both filter and espresso as i have a niche zero and prefer it for bodied brews.

thanks

I have a Kopi Deva from the Indiegogo campaign. It originally came with HU burrs which I've just switched for SSP Cast burrs. I also have a Niche for the same reason as you @bolido21.

Firstly, I really like the grinder. The workflow is fantastic for starters. I would say it rivals the Niche. Coming from a Niche I've had many disappointing grinders that required too much work for acceptable results.

The quality of the espresso is also really good. I'm not an expert but it's far better than any grinder I've owned before. I found the HU burrs disappointing. They were definitely a bump in clarity over the Niche but not enough for me. That's why I then fitted cast burrs which are perfect for my tastes. Another bump in clarity, more sweetness, pretty much what most professionals say about them. You lose texture but not as much as, say, an EK43.

I don't drink filter enough to give a proper opinion on that.

Hope that helps.

I should mention that it was Grizzleys post on retention in the funnel that brought me here. I have the same problem. A couple of pulses of the motor are no effort. It's not a dealbreaker but it's very frustrating how sensitive the retention can be to the way you shape the wipers. I wouldn't be surprised if Brandon or someone with a 3D printer fixes this soon. It's the only niggle I have of an otherwise fantastic grinder. It's early days though and I'm going to persist.

I know this thread is long and near death but I thought it fair to post an update on my experience. Kopiconcepts have been very helpful with the retention problem and sent me a troubleshooting guide and followed up with a few tips. After changing the wipers, checking their length and orientation, the change was quite dramatic, with virtually nothing left in the funnel now. I've posted a photo.

I know this may not be for everyone but for me the quality in the cup has been worth it. And to be fair, it's pretty good for v1 of a pretty novel design.

Thanks, Steve. Funnel looks great. Wondering if you could share a pic of your wiper adjustments, and/or lengths, or did you do exactly as in their guide? Mine seem right but there is retention (even with RDT). [Edited to add quote for clarity.]
