wow, too stupid to operate a coffee grinder and blame it on the grinders’ design, lol.

So, i try to give some info.

The opening could be bigger, but the deva comes with a shovel that feeds the beans very well.

Then, the design of the grinder is described this way: “Our patent pending design creates a small pressure difference between the burr chamber and the exit chute, encouraging air flow through the grind path to help the pursuit of zero retention.”

That makes all grounds fall out of the funnel after grinding. No bellows needed. That is explained on the Deva page. You can also see it in the video

Absolutely insane to see that as a con against the grinder. I absolutely love it. It is the cleanest grinder i have ever used.

If you do not want it, i would take it as a friend of mine wants one badly after having used mine.

    ez4prez well the campaign has closed so a refund/cancellation isn’t guaranteed. you’ll have to ask them directly and wait upon a decision.

      mackerel I agree and the criticism is somewhat amusing, too. “The grinder sounds like a$$ when running..” which begs the question, what is the best a grinder could sound? No sound at all? Now that would be cool. A few folks have mentioned the grinder is pretty quiet which would be a benefit.

          Sounded fine in the video… I even think the funnel is good in that it’s easier to clean than most grinders’ chutes. The point about beans sticking still concerns me though. Just don’t wet the beans? But the creator does it in many of the demo videos…

          Do you wet your beans before feeding @mackerel ?

            From a previous user of a sette 270 and a current owner of a niche… the deva is just delicious to use.

            Hell… I am single dosing 72g each batch at work. Basically keep feeding the little sucker until you empty your cup and never had beans sticking inside even with RDT.

            I am starting to think people basically immerse their beans in a cup of water prior to grinding them.

            those complaints seem rather made up to an actual user of the Deva.

            Can’t take that serious.

            Hmm very tempted to enquire about the discord user’s offer to sell now… especially with p64’s being hard to find used and having long lead times…

              hthec

              Person considering selling lives in the SF Bay Area of California and goes by discord handle baleong#2299, but if you’re in the UK that might not work. They also prefer their P64 which they readily admit is 2x the price. So go figure.

              Frankly, I’m not sure what to make of these wildly divergent opinions. Ugh. Maybe I’ll just keep my order and if I wind up in the camp of people who aren’t thrilled with it, then resell it. But I certainly hope for my sake that I’m as delighted as you all are.

                I have the Lagom P64 at almost 3x the price of the Kopi Deva.

                  Anyone here have the espresso kit add-on? If so, any thoughts on it. I figured the dosing cup would be adequate but now thinking I might ask if I could add the espresso kit.

                  One thing I would say is that one of the users having issues on discord is borrowing it and I think people are more likely to be forthcoming with issues in that situation. Not saying you guys are but it’s easy to talk yourself into thinking everything is fine when you’ve invested a lot of money in something.

                  I’m trying to understand the explanation for why the coffee doesn’t drop until the end That can’t be a good thing for retention right?

                    The different pressure is built up on purpose and when you stop grinding it releases and takes the remaining grounds with it. As you can see in the video most of the grounds fall out while grinding.

                    No idea what is so difficult to understand. No need for bellows with the Deva and that is a great thing in terms of looks and operation.

                    Guy just seems to not have informed himself in regards of how the Deva works and blames his own errors on the design of the grinder.

                      mackerel if there’s an intentional pressure difference then that means that suction is holding the grounds in place, correct (but surely impossible)? Or basically, if it’s simple to explain, can you explain how this differential is created and why it does what it does please?

                      I mean, the guy is using rdt as per the manufacturers instructions, what are you implying he’s doing wrong?

                          nah, not spending more time on this nonsense, sry.

                          The grinder is working the way it should be. End of story.

                          Move on, buy a different grinder. No problem.

                            Hmm let’s see here. 18.4 in and 18.4 out and with rdt too.

                            Given my country humidity is practically always high, i don’t RDT.

                            Once you familiarise yourself to the work flow, there is practically zero retention.

                            The higher RPM will cause a higher differentiate pressure difference holding more grounds in the funnel, however most of the it falls upon turning off the grinder. Usually for higher RPM, i will start/stop the grinder once or twice to allow for the last few 0.1 g of coffee to fall. The additional step is not needed at lower RPM say 600 and below.
