Review consensus · sourced & dated
What reviewers say about the 1Zpresso K-Ultra
Only one whitelisted tester (Tom's Guide) published a hands-on K-Ultra review; its ex-barista reviewer rates it among the most uniform hand grinders she's used, with Kruve-sieve-verified consistency, measured 1.8% average retention, and a travel-friendly folding handle plus hard-shell case. Downsides are considerable burr static after grinding and a fiddly, time-consuming fine micro-adjustment beyond the default range.

the 1ZPresso K-Ultra is one of the best I've ever used, hands-down.
there was a considerable amount of static on the exterior of the burrs after grinding.
I found this a little fiddly and time-consuming, so I wouldn't recommend doing this for everyday brewing.

How we checked
Verified 2026-07-07 by re-fetching both pages with fetch-clean.mjs. Model confirmed exactly K-Ultra (not a K-series/J-Ultra/X-Ultra sibling) on both pages (Amazon Model Number "K-Ultra Iron Gray with Carrying Case"). 1Zpresso store page confirms: manual grinder, heptagonal conical stainless-steel "K Burr", "Over 100 clicks with 20-micron precision per step" via the external adjustment ring, foldable handle, Weight 700g (=1.54 lb), Grounds Capacity 35~40g, current price $259 (original $289). Amazon A+ corroborates: stainless-steel conical burr, "48mm Stainless Steel Burr", "over 100 clicks ... 20 microns per click", external adjustment, magnetic catch cup holding 35-40g, "All-Round" brewing method, and "$259" in its comparison chart (the buybox itself showed EUR for a Germany locale; the A+ chart lists the USD $259). burr size (mm) (48) is sourced only from the Amazon A+ content since the store page omits burr diameter. grind settings was corrected: neither page supports "per rotation" (both state "over 100 clicks" total), so the value now reads "Over 100 clicks (20 µm/click), external adjustment dial". weight (lb) 1.54 is the exact conversion of the store's verbatim 700g (Amazon rounds to 1.5 lb). hopper capacity (g) kept at 40 as the verbatim upper bound of the 35-40g grounds capacity. No release date/year appears on either fetched page, so release date/release stay blank. 7 of 8 spec keys survive.
