1ZpressoK-Ultra Manual Coffee Grinder Iron Gray with Carrying Case, Assembly Consistency Grind Stainless Steel Conical Burr, Foldable Handle, Numerical External Adjustable Setting, All-Round Grinder

This is my second grinder to replace my cheap grinder, the HEIHOX, which uses common burr found in many grinders like Timemore C2. The quality and ease of setting the grind level is the best as mentioned by other reviews so will focus my review on taste and if it's worth the upgrade.I have done tests between the two grinders using Aeropress and the results led me to conclude it all comes down to what you like. The cheap grinder gives sweeter and fuller body but less clarity, meaning no separation of various taste notes. K-Max tend to produce lighter body but more clarity because you can taste all the various flavors such as fruity and floral notes in fresh Ethiopian. If you like Ethiopian, then K-Max is great. I like having both grinders to be able to change things up but I enjoy both.Some have said it's easy to clean and calibrate. I'm very technical person and I can tell you it's not that simple. You need to read and follow directions precisely. I ended up locking it and had to send it to 1zpresso to unlock it. At first they weren't going to cover the cost but did so after I showed them that following their instructions caused it. They agreed and they updated their instructions since after they asked me to review it. I have to say they did a great job supporting their product and they're very friendly to work with, which you won't get with cheap grinders.Is the K-Max worth it? Definitely! Its smooth and fast operation is the best so grinding experience is more enjoyable. It's preferred for high end coffees because it is able to better extract flavor nuances from the beans while giving pleasant grinding experience.

My husband and I have always loved coffee and wanted to dive into pour overs and other brewing methods outside of your typical drip coffee machine. We have a regular blade grinder that we thought was great before we cared about how our coffee came out. After doing a lot of research, this was one of the top recommend hand burr grinders based on our wants/needs. Maybe it’s the whole process, but the coffee came out amazing and you can really taste the flavors of the beans this way.This grinder is very easy to use and doesn’t take long to grind at all. It definitely takes some calibration at the start and every now and then sheer cleaning. It comes with a nice bag that makes it portable and you can use it wherever because it is very quiet. We plan to take it with us whenever we go camping. It might seem expensive, but it is great quality and worth every cent.

Purchased after a ton of research, used primarily for filter coffee, manual espresso on weekends (primarily macchiatos)The k-ultra is a best-in-class hand grinder capable of excellently uniform grinds at a huge range of sizes.I upgraded from a Timemore C3 and immediately noticed a tremendous difference in my cup.This grinder is capable of achieving extremely chocolatey and extremely fruity cups with ease.It's a hand grinder, so the best results aren't as repeatable as an automatic, but the highs are higher and lows aren't that low.Magnetic catch cup isn't nearly as worrying as I thought it would be in person, (that's not to say I haven't managed to spill it.)parts are of high quality and easy to clean, disassemble, reassemble, and zero.the handle part does get slippery after only a little use but it hasn't popped off during grinding for me, it's just looser than I'd like, not an issue though.After a few months of heavy daily use, I haven't noticed any deterioration of any of the parts except the aforementioned top bit.The K-ultra does its job grinding fine enough to dial in espresso, and coarse enough to dial in filter coffees. I've tried with everything from turkish to french press, (and everything in between except moka pot and siphon) and can confidently say it's good enough for all methods. I'm sure I could get 2% more quality from a 2k+ automatic monster but I'm more than happy with this thing.It's easy to crank and doesn't take too long even for large doses of espresso.Although thanks to Lance Hedrick I'm slow feeding now which more than doubles the grind time (but OMG the clarity.)

Like this one, my third hand grinder. Like the magnetic cup, the exterior grind number setting scale, the size of the magnetic cup (will hold 40 grams, usually do 34 grams for two big cups.....the top of the grinder only holds about 28 grams at one time), & the folding handle. It took me 3 different You tube videos before I could properly Calibrate the number scale for grinding, but I eventually got. Use a setting of #9 for fairly Coarse Pour Over Hario Switch V60 coffee making. A Consistent grind in daily use. Heavy, sturdy construction....and its bigger than it looks on line. Impressive

The 1Zpresso K-Ultra has exceeded all of my expectations as a manual coffee grinder. From its sleek iron gray design to the thoughtful engineering behind every part, this grinder offers an outstanding coffee experience. The carrying case is a nice touch, making it perfect for traveling or keeping it safe in storage.One of the standout features is the foldable handle, which not only saves space but feels sturdy and comfortable when grinding. The external numerical adjustable setting is incredibly precise, allowing for seamless adjustments between different grind sizes. Whether you’re grinding for espresso or pour-over, the stainless steel conical burr delivers a consistent grind every time.It’s clear that a lot of care went into the build quality. The grinder feels durable and solid, and the overall grinding experience is smooth and easy, even when handling tougher beans. Plus, the disassembly for cleaning is simple and hassle-free.If you’re serious about your coffee and want a portable, high-quality grinder with consistent results, the 1Zpresso K-Ultra is an excellent choice. Highly recommend it for coffee enthusiasts!
