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.

simonc Kopi Deva advise that a slower RPM gives a more uniform particle size which slows the shot down.
So maybe 0 grind setting and 500rpm rather than 700 rpm will give a 38 second shot time but then doesnt changing particle size distribution affect the taste. ie more/less clarity, more/less body.

MattH

Kinda sounds like excuses .. if you have to use a certain speed - its not really a variable RPM is it ? What happens if you run it full speed ? - Oh I see you did - it does not make a-lot of sense ?

simonc

Good point, hadn’t thought about it like that. Or rather, its I can’t use a certain speed as it doesnt necessarily give the best taste for that RPM, ie a shot of either 30 seconds or 40 seconds, no option for 33 or 36 seconds for instance.

(My machine has 10 second pre infusion so generally go longer than 30 seconds which I mean from turning on the pump to turning off. not counted on drips etc)

FadedFrontiers

simonc what espresso machine are you using and have you had this issue with other beans? Doesn’t sound ideal though as judging from other posts it should have more espresso control, so if you’re sure it’s not a beans or espresso machine issue I’d insist on a replacement at the very least.

simonc

FadedFrontiers I have an ACS Minima. As I said above, I can get a 3-4 second change in shot time on my Niche Zero on same beans.

Also a lesser but still annoying issue. Sunday, I turned on the switch at the back to connect the battery. Showed 50%. 2/4 lights. Ground and made 2 coffees. over an hour Left everything on, and went to make another coffee 30 mins later and the grinder battery was dead. I am sure they will say to turn it off at the switch but really wouldn’t expect battery to die that fast when it’s only really lighting up 2 little blue LEDs.

Been told they dont do returns for pre-orders but I wouldn’t be returning as I dont like it, but that it doesnt function as a £800 grinder should do for espresso. And they offer espresso accessories so clearly marketed as an espresso capable machine.

FadedFrontiers

simonc yeah that doesn’t great, how much do RPM changes alter shot time with same grind setting, in your experience?

I add say that the NZ is completely different with it being a conical (and a very forgiving one) so not totally comparable, flats can be tougher to dial in and more sensitive to changes in my experience.

I also didn’t think the minima had any PI chamber or setting, are you using flow control?

Cuprajake

wow, thats poor

it should do as intended or its not fit for purpose. and its not like you can sell it onto someone knowing it wont grind for espresso

have you tried different burrs in there?

simonc

Cuprajake glad it’s not just me. No, the standard burrs, which as recent direct order, rather than Kickstarter, are Mazzer Super Jolly.

Yeah, hard to sell unless maybe as a filter only grinder, but limits market on already a bit of a niche product.

simonc

FadedFrontiers yes true, but just indication that the beans aren’t crazy to grind and yes on my old flat burr I could adjust for 3-5 seconds easily.

Maybe I am wrong, yes I have flow control, but not using whilst I sort out the grinder so keep consistent. I see the machine doesnt start increasing pressure beyond 2 bar until maybe 8 seconds and hits full pressure at 12 seconds.

FadedFrontiers

simonc yeah that’s the best thing to do as flow control can add variables. Really seems like you got a dodgy unit.

Out of interest has seasoning the burrs so far improved things at all compared to day 1?

mackerel

I have the grinder for 20 months now and never had any of those issues.

I have a programmable espresso machine and the shots always end within .5 secs.

Only drinking espresso as well. Could not be happier with the grinder.

Cuprajake

mackerel yeah but that doesnt help him,

@simonc see if you can find some genuine burrs to put in there and see if it helps, you may have a dodgy set of burrs

simonc

mackerel that’s good to know.
What sort of adjustments do you use to dial in? I’d are you adjusting down to fractions of a 0.1 marking?
Do you have to adjust rpm to dial in. (Rather than liking to)

simonc

Cuprajake I think they are now supplying original ones not copies

mackerel

well first of all I adjust the amount of beans. Depending on the kind of beans and the age, I put between 19 and 20.4 grams into my 18 gram basket. After that it’s grind size. The 100% canephora beans last week had to be ground much finer than what I usually use.

And yes I adjust between .1 markings.

Rpm can also be used to do fine adjustments.

simonc

mackerel cool. I’m keeping dose fixed for now. What time difference does a 0.1 change make for you?

simonc

FadedFrontiers maybe a little on consistency but not a lot. Consistency is very good.

mackerel

simonc I can take the time tomorrow

mackerel

Time difference of the shot was 2.6 seconds when grinding .1 finer.

simonc

mackerel that’s very precise. Thank you.
I think another user earlier said they see about 3 seconds per 0.05 so sounds similar. That is what I’d expect and sounds then very useable.
Very different to the 20-30 seconds I’m getting per 0.1

I’ll go back to them again and see if they will replace the unit. Is clearly faulty.

Also said I’d be happy with a replacement but don’t want to spend another 6 weeks testing and fiddling and having sub optimal coffee for them to decide if it’s working or not. Assuming they even accept this one isn’t.
