Manual Burr Coffee Grinder with Stainless Steel Conical Burr, Consistency Grinding, Mini

Good grinder. Well built, very smooth operation, appears to be consistent. Happy to use every day.Loses 1 star because when you charge so much the standards are higher. A ceramic burr grinder with a plastic body is $25, so 5x more should buy perfection.Three relatively minor annoyances that the makers should have noticed.First, the pretty round ball handle looks great, but it means an awkward and weak grip. A pole that sicks straight up would mean the user can grab the crank like a butter churn and use far stronger muscles to turn the crank. On the other hand (literally) the small knurled area on the grinder means you cannot use this grinder if you have weak grip strength. There is no way to get mechanical advantage as an alternative to a strong grip.I think poor ergonomics like this is why manual grinders are so rare. They're hard to turn because you're forced to use small weak muscles.Second, there's no clear way to consistently grind only the amount of coffee you need without resorting to outside tools like a scale. The hopper is too large for a single shot in my portafilter, yet too small for two shots, and it's hard to see how far in the hopper you've filled. This means you end up using yesterday's grind for half a shot. Not a big deal, but at $150 a simple glass window or other gauge would be very helpful.Finally, the grind adjuster could use a better design. The nut can be hard to grab if you have large fingers because you have to wedge them against the sharp metal edge of the grinder body. A simple wing nut design would be extremely welcome. Similarly, some way to read off an absolute number would be extremely useful if you have to go between different grind levels often. The only way to do that is to count the number of turns to tighten the adjustment nut, but that's cumbersome especially if you have large fingers. This can be simply solved by having the adjustment expose a line for every turn so you can simply count lines.

I've had this grinder for a couple of months now and I love it. I use it mainly for espresso - with the Flair - but I also use it with an Aeropress. My roommate uses it for pour-overs. We also have a Knock Aergrind, but we've pushed that to the back of the shelf.Pros:Consistent grindStepless grinderEasy dial-in for espressoEasy, fast grindQuick disassembly/assemblyEasy, thorough cleaningGreat price for qualityCons:No big ones(see below)This grinder produces a consistent grind (more consistent than the Aergrind) and it's a dream to use. It grinds faster than the Aergrind, and the wooden handle and length of the crank arm make it easier to turn.Why is it so expensive, compared with the $20-60 grinders on Amazon? Because it has metal, stainless steel burrs. Those cheaper grinders have ceramic burrs. This grinder's stainless steel burrs are also mounted on a hard, no-nonsense stainless steel body.With a ceramic burr grinder, it takes me 4 - 5 minutes to grind 15 grams of coffee for an espresso. With those same ceramic burrs, it takes me 2 - 3 minutes to grind 15 grams of coffee for an Aeropress.With these steel burrs, it takes me 40 - 50 seconds to grind 15 grams of coffee for an espresso. Or, I can churn out an Aeropress in 20 seconds.This 1Zpresso is a stepless grinder. That means there are no "clicks" to position your grind adjustment. There is just a smooth wheel motion. Stepless means I can make micro-adjustments, which are helpful with espresso.The grind adjustment is on the bottom of the grinder, inside the catch cup. The adjustment wheel isn't super easy to turn by hand. I keep a coin next to it to turn it.The catch cup is screwed on. I prefer that to the Aergrind and many ceramic grinders, which just have a gasket. With those, you push the catch cup on and hope. They often slip and I have to hold them with at least some of my fingers while I'm grinding. I don't like the feeling of something wiggling around like that. This one is solidly attached and screws on and off easily and smoothly.The instructions are pretty easy to follow. I use one full turn plus 1 or 2 more reference points for most espresso shots on the Flair. For Aeropress, we prefer one full turn plus 5-7 more points.This grinder is also super easy to clean. I rotate the catch cup one way and the top half of the body the other way. The burrs are mounted on a central, steel ring. I can easily brush out the burrs or use a compressed gas air duster (the same type I use on my computer keyboard). I clean the burrs after almost every grind since I do quite a bit of home roasting and some extra chaff accumulates. Plus, I hate the smell of rancid coffee.I'm posting photos of what the grinder and the burrs should look like when disassembled. I just tried to purchase the E-Pro grinder from 1Zpresso, here on Amazon, and the burrs were not as they should have been. I don't know if someone is selling fake 1Zpresso grinders or if 1Zpresso is cheapening its product, but watch out. The company's website shows that all of its grinders should have this type of basic structure. You should be able to easily disassemble the grinder and see the burrs mounted on a central, horizontal axis. I wouldn't buy one of these grinders if it didn't have that structure. I think that's what makes the grind so consistent.There are only two small negative comments. First, as one reviewer pointed out, the rubber gripping band that came with the 1Zpresso grinder was almost impossible to slip over the grinder's body. We ended up just taking the rubber gripping band from the Aergrind and slipped it onto this grinder. You could use a thick rubber band as well. I don't think it's a deal-breaker, not for the quality of this grinder. Second, the wooden handle occasionally pops off when I grind. It never pops off when my roommate uses it, so it must have to do with the angle I'm using. Again, it's not a deal breaker for me.I wouldn't hesitate. If you want a cheap ceramic grinder, this isn't for you. If you want an electric grinder, it isn't for you. If you want a high-quality set of steel burrs at a great price to go along with your high-quality coffee to satisfy your home barista moments, this is for you.

The quality of this manual coffee grinder is very good. The burr is made of stainless steel, which is much easier to grind than ceramic ones. You can easily dissemble it completely to clean. It takes less than 1 minute to grind enough coffee for one cup.The design is sleek and the color is great. It's pretty light and small. It's very convenient to use either at home or when travel. I got it for almost a year and use it on most days. Very happy with it.The only drawback is that there's static electricity, which makes a small amount of powder sticky to the insider of the powder container. Have to use the brush (coming with the grinder) to remove the powder. I'd give this grinder a 4.5 out of 5 if this score is available.
