They started shipping them today. Anybody kickstarted it? ![A zero waste coffee grinder - engineered to the precision of a Formula race car. Literally.](https://ksr-ugc.imgix.net/assets/033/083/609/57fe7dfb9833c595341b7f015564c4aa_original.jpg?ixlib=rb-4.0.2&crop=faces&w=1552&h=873&fit=crop&v=1618172524&auto=format&frame=1&q=92&s=1075a8fbb5057244b2b2d499568e9260)

I am in lust. Would have been very very tempted had I seen that on Kickstarter at that price. Am sure it will be a lot more retail.

I considered getting this, but it being battery powered put me off to be honest. Does look beautiful though.

They're still available on indiegogo. Looks beautiful I agree. I'm waiting for early reviews as beta testers reported some issues like grind retention in the funnel, excess static, etc. Then if those are fixed to convince myself I need to upgrade on the eureka…

Battery powered?! How was that determined the most appropriate course of action? I appreciate 3kg per charge is probably about 3 months for most people but still… As above, it’ll be interesting to see how it deals with the usual grinder related complaints like static and retention.

Well i wouldn't worry about battery, have you seen an sds drill go through concrete 😂 Its a stunning little grinder, while not a fan of the sweepers, remind me of cable ties .. But it could be a little gem.

> @"Cuprajake"#p14108 But it could be a little gem. Isn't it a belt drive? I also remember the praise being heaped on the Lagom Mini, so it's best to actually see what it really does.

@"Cuprajake"#p14108 Your point about the drill got me thinking… Presumably if it’s not running on constant voltage, as the battery wears down the motor rpm will reduce, as with a cordless drill? EDIT: I just read the blurb and apparently it uses an ‘intelligent battery management system’ to regulate the power to the motor so it’s consistent as the battery drains. I wonder if the cordless approach was to avoid having to consider different voltages worldwide and ship the same product globally.

@"Ernie1"#p14125 It's an induction motor I think, so shouldn't slow down. my concern would be about the batteries…are they replaceable, did they use 18650 cells etc.. as they will have a limited lifespan. They have not stated the grind times by speed ranges either?

@"DavecUK"#p14127 Indeed, interesting they specifically talk about sustainability being ‘top of the list of design priorities’ but then use a disposable power source.

> @"Ernie1"#p14129 Indeed, interesting they specifically talk about sustainability being ‘top of the list of design priorities’ but then use a disposable power source. I guess they wanted it to be portable…the main thing to find out, is what they are not telling you! It certainly looks nice.

LMSC Yes it works really well, the only thing I dont like is that you need to “fiddle” a little to get everything out, I usually need to turn it on/off or decrease/increase the rpm about three to five times to get everything out. Just takes some seconds so not the end of the world but would of course prefer if everything just came out without doing anything.

that is exactly my experience in terms of retention. I cleaned it once (incl. disassambly of the burrs) after 2 months of use and will never do it again. There was basically nothing i could clean.

also i have absolutely no static. maybe i am a fanboy, but i am just impressed with the grinder. It is quiet, has rpm control, very clean and makes good coffee. Imo much better than DF64. P64 level for half the price.

I couldn’t be happier. Sad, that @powderhorn doesn’t have the same experience. But he should be able to get it solved with the Deva team. They are very nice to deal with.

turning the grinder on/off two to three times is not a big deal for me. much better than having to use bellows.

Tjyven Mine was good from the start, with an input of 20g my first five grinds had an output of 19.9, 20.1, 20.0, 20.0, 20.0.

LMSC It’s what you will see with quite a few single dose grinders, pretty normal for that scenario. You could see even less variation if the 0.1g scales have a larger accuracy/precision than the units they read in.

MWJB It’s what you will see with quite a few single dose grinders, pretty normal for that scenario.

If f the burrs are set at an angle or something similar to what these users do. Otherwise, if the burrs are set flat, there is going to be some retention when the grinder is run the first time after cleaning. No?

powderhorn While I understand if it happens with darker roasts / French roasts, I won’t expect a medium roast to exhibit this behaviour - not oily and unlikely to stick as much as the dark. I remember some early adopters of Solo DF 64 sharing similar experiences elsewhere.

powderhorn

So, I reckon it must be the beans, What beans do you all use? I have tried a dark French roast, and a medium Columbian. I take it you all must be drinking lights?

i drink medium to dark roasts.

Difficult to say without accurate measurement of that specific grinder.

Tjyven

Only had mine for a few weeks and into my second bag now and both have been in the area om medium to medium dark.

If anybody is trying to order one, it looks like they added another run of indiegogo reserve units for Q12023:

Gone some months now and I am curious of what burrs other users prefer. I have tried SSP HU and Mazzers Food Friendly, both are good but I prefer the profile from Mazzer. Almost only drink espresso but you who also drink filter coffee what burrs do you prefer?

rytopa

Tjyven So far i only have the Stock burrs to play with.. I am really enjoying the output from this grinder, from Workflow to Taste. The espresso flavours are very well balanced/sweet and smooth. Clarity is certainly not its strongest point, but the balance and sweetness easily makes up for it.

Interested for filter using this stock burrs also provides very good brews. The Mazzer style burrs, when used in conjunction with this grinder, outputs very little fines which is very surprising, given the experience i had with other grinders with similar burrs.

Tjyven

rytopa Agree, the Mazzer style rally gives a sweet and balanced shot, while the SSP HU gives more clarity. What RPM are you using? With few exceptions I have high RPM (1000-1200) for espresso, but for the rather few times I make filter coffee I have found that lower RPM gives better result.

rytopa

Tjyven My RPM is generally Max at 1200 rpm for espresso and around 200-400 for filter.

Depending on coffee the Max RPM tends to blend the flavours, decreasing alot of harshness for coffee which are of lesser quality or roast. Recently i had a Tim Wendelboe espresso roast which tasted very muted at higher RPM, lowering the RPM brought out the acidity and characteristic of the coffee.

Cuprajake

I find my Hu SSP give more acidity too

Tjyven

rytopa Same experience as me, normally I think high RPM gives the best results but for few coffeys I think that high RPM gives a little muted taste and then the result will be better with lower RPM.

Oops. I’ve just pre-ordered one for Q4

MattH

Looks like a interesting grinder - for not crazy money…

simonc

I hope so…. another 3 months on, how are people finding it? My budget only stretches to the stock Mazzer SJs

Tjyven

simonc No complaints, it is a very good grinder!

simonc

Just seen this on Instagram. Looks like there might be a review of sorts coming soon from this coffee shop that has been lent Brandon’s grinder to use for a bit.

simonc well this is disappointing as a review. I guess Brandon’s sister drove it to them and waited and took it back. doesn’t sounds like they used it much and sadly no detailed review of workflow, cleaning etc.
