Good adjustability, well built
Incredible service and experience! Still getting dialed in but the coffee comes out great anyway
Grinds 18g of medium-dark roast beans in less than a minute. A definite upgrade from the Kingrinder P2 I had previously.
Excellent grinder delivered surprisingly quickly with no import delay or unexpected customs charges. Overall, excellent value for money.
I am very pleased with the quality of the K-Ultra Manual Coffee Grinder. I purchased it to replace an electric burr coffee grinder which I had for several years. I decided to look at manual burr grinder options. After considerable research I chose the K-Ultra from 1Zpresso. The quality of the coffee experience I now have is far superior to what I had from the electronic burr grinder. If I were to make a suggestion it would be to make available a “video for dummies” on how to use the K-Ultra Coffee Grinder. Basically it would cover everything from opening the package, to assembly, cleaning, calibration, etc. I am visual person and would prefer that approach and still have online documentation as a backup. I was able to find some third party videos on You-Tube that helped me out.
I love my grinder! My only complaint is the ball on the end of the handle has fallen off. It popped back on and seems to be ok for now, but based on comments from other owners, it will most likely be an ongoing problem for me. The grinder is fantastic otherwise, though!
As a first time shopper with 1Zpresso, I had an amazing experiences with them. When i had an issue with my order, Samuel and their teams communication was very professional and transparent and the issue was promptly solved. When I finally received my K-Ultra it was a night and day difference with my old grinder, Sure it did cost a bit more compared to my old grinder but I feel it was defiantly worth every dollar. The K Ultra feels very premium and using it felt quite easy and smooth I am still dialing it in to fit my taste better, but so far been loving it.
