Finds their K-Ultra kills their Kinu and Ode, though they still use the Ode more on rushed mornings.

“K-ultra 1zpresso owner here. This balls out kills my Kinu and my Ode.”
positive

Got great brews from their K-Ultra out of the box without seasoning, at around 5.3 for a 20g V60.

“I honestly haven't had the experience that others are talking about where the grinder doesn't taste as good until it is seasoned. I was getting great brews out of the box.”
positive

Regrets getting a K-Ultra instead of a ZP6 as they've struggled with it, finding it unimpressive for light roasts.

“kinda regretting getting my K-Ultra instead of the ZP6. i’ve been struggling so much with my K-Ultra”
negative

Moved up from cheap Timemore grinders to a K-Ultra and can't believe the clarity in the coffee.

“last week I finally bought an 1zpresso K-Ultra. I still can't belive the clarity in the coffee, it's simply amazing!”
positive

Uses their ZP6 for washed light roasts and geishas and a Pietro for everything else, no longer touching their K-Ultra.

“ZP6 for washed light roasts and geishas, Peitro for everything else. I don’t even really touch my K-ultra since getting the Pietro.”

Rarely uses their ZP6 now and prefers the K-Ultra, as they mostly drink anaerobic naturals.

mixed

Calls their K-Ultra one of their top three least disappointing purchases ever.

“I have a K-Ultra and it's probably in my top 3 of "least disappointing purchases ever”
positive

Bought a K-Ultra and Chestnut S3 as travel grinders and ended up liking the K-Ultra much better; its cups are well blended.

“i bought the s3 and k ultra just for my travel grinder but ebding up liking the k ultra much better than the s3.”
positive

Replaced a six-year-old Encore with a K-Ultra and found it worth every dollar, with no more astringency from fines.

“Last week i bought a 1zpresso K Ultra and i can tell You: it worth every dollar i spent. The most obvious change i could notice was that there's no more astringency caused by fines.”
positiveconsistent

Their K-Ultra is their endgame grinder; upgrading from a Timemore C2 was night and day.

“is my 1zpresso K-ultra. I upgraded from a Timemore C2 and it's night and day.”
positive

Light RDT over four months rusted two bearings in their K-Ultra, one not replaceable without special tools, and 1Zpresso refused to help.

“Careful use of RDT using a minimal amount of water over ~4 months rusted two of the bearings in my K-Ultra, one of which can’t be replaced without specialised tools.”

Their K-Ultra tasted great straight out of the box without seasoning.

“I did not season my K-Ultra and it tasted great right off the bat.”

Of their Ode 2, ZP6 and K-Ultra, the K-Ultra is their favourite: more interesting, forgiving and consistent.

“My favourite among the three is the K-Ultra. I find that it’s more interesting, forgiving, and consistent than the other two.”
positiveconsistent

Has owned a K-Ultra and ZP6 for two years and enjoys 95% of coffees equally on both; if keeping one it would be the K-Ultra.

“If i were to have to choose to keep only one, it would actually be the kultra for me.”
positive

Started on a ZP6 but their K-Ultra has replaced it as the daily driver.

“Kultra has dethroned the zp6 as my daily driver based on my personal preference.”
positive

Uses both a K-Ultra and a ZP6; if they could keep only one it would be the K-Ultra.

“I have both, use both. If I could only have one, it would be the K Ultra”
positive

Owned both and preferred the K-Ultra, which makes juicier cups and works better across different beans.

“It makes much juicier cups & better all around for different beans”
positive

Their K-Ultra can do espresso, making good traditional shots and superb turbo shots.

“My K-Ultra would like to confirm it can spro, it has made good traditional espresso and some superb turbo shots”

Absolutely loves their K-Ultra alongside an Ode Gen 2; manual grinding is quieter in a sleeping house and not hard to crank.

positivequiet

Had poor pour-overs for nearly a year with their X-Ultra until they realised they were grinding too fine.

A few weeks of daily espresso and French press with their K-Ultra and it's been great.

“I got my K-Ultra two years ago, and while I’m not making world-changing coffee every morning, it is generally a ‘good’ cup”

Their K-Ultra no longer gets used: always flat next to their other grinders, okay at espresso and pour over but great at neither.

“the K-Ultra does not get used any more, its always flat compared to the other grinders”
negative

Uses their K-Ultra and ZP6 equally; the K-Ultra makes bolder cups.

“They make a totally different cups so it nice to have a variety. Ultra makes bolder cups and ZP6 makes lighter, cleaner cups.”

Their K-Ultra was an excellent grinder, but at Brazilian prices they sold it for a modified cheaper grinder they liked as much.

mixed

Getting sour, hollow brews from their K-Ultra and can't fix it.

“I’ve been getting sour hollow brews with my k ultra too idek how to fix it”
negative

Added a K-Ultra alongside a Pietro and recommends it to anyone with a high-clarity grinder, especially for beans that taste bad on the Pietro.

“I just wanted to say if anyone has a high clarity grinder and is thinking about getting a k-ultra or similar. YOU SHOULD!”

Owns a K-Ultra and loves it; hand grinding about 20 seconds per dose is part of the ritual after five years of manual grinders.

Really likes their K-Ultra: switches easily between AeroPress and espresso and tastes clearly better than their Breville's built-in grinder.

“I also really like it, can switch between Aeropress and espresso pretty easily and one dialed in, I can really taste the difference over the built in Breville grinder.”
positive

A week into a K-Ultra after a K6: more florals and clarity but less sweetness, and they prefer more balance.

“I’ve been noticing a lot more florals in my cups and less sweetness than the k6.”

A co-ferment they couldn't get right on a Femobook A4Z was amazing first try on their K-Ultra, which they use for co-ferments and naturals.

Just bought a K-Ultra and will probably return it, unable to get decent results whatever they try.

“Just gotten myself a K-Ultra and I will be probably returning it as no matter what I do I can't get decent results.”

Four months with the K-Ultra and very impressed with how it improved the flavour and texture of their coffee.
