M-MAX Burr Coffee Grinder,Professional Wireless with One-Click Grinding & Adjustable Coarseness,Portable Mini Coffee Bean Grinder for Home/Office/Travel,Black

If I was to shop around for grinders again I would not purchase this.It works well and has a good design.However, the way to adjust the grind doesn’t make sense. There’s no “levels” you just twist and hope that it’s at the right grind size. It grinds really slow and takes quite a while. Also the battery isn’t great. Probably can do one full cycle of beans then needs to be recharged.

This is garbage, don't buy it, It takes 10 minutes to grind a cup of coffee! Each grinding takes only about 30 seconds and sometimes it's 2 minutes. This is absolutely insane.It broke down on the third day of use. I charged it overnight, but the battery failed.

I ordered this coffee grinder as my old one is getting pretty rough. This M-MAX delivers for the most part. It is portable, compact and lightweight, so it’s very travel-friendly. I would take it on vacations because I prefer fresh ground over motel coffee. It’s rechargeable and it will last a few days on a trip. It could be used at the office or work break room. It holds more than enough beans for a full pot but it doesn’t take a lot of space on my kitchen cabinet. It has a wireless design so no cord clutter. It’s black color matches my kitchen appliances and it is a very smart looking appliance. Operation is easy with the one push button to start it grinding. The M-MAX uses a burr grinder which uses less heat and not as much vibrating as the blade grinders. It gives me a more even grind so I’m getting the most out of the expensive beans. The coarseness is adjustable and that covers a range of brewing types like coarse grind for the French Press or fine for espresso drinks. You make your coffee exactly how you want it.The grinder comes apart, motor from the bean bin, and is easy to clean. I like that it is cordless. I very much like that it is the quietest grinder I’ve ever had.

This wireless coffee grinder is super portable, fitting easily in my bag for travel or office use. The one-click grinding is quick, and the adjustable coarseness dial lets me tweak from fine for espresso to coarse for French press. It grinds enough for a couple of cups in seconds, and the USB charging is handy. The stainless-steel burrs feel durable, but the grind consistency isn’t always perfect—sometimes I get uneven grounds, especially on finer settings. Cleaning is simple with the detachable parts, though coffee dust can stick in crevices. For the price, it’s a solid deal for fresh coffee on the go, but don’t expect pro-level precision. If you want a compact grinder for home or travel, this one’s practical despite minor quirks.

Decent small grinder but takes a very long time to grind, especially if you want finer grinds.

I would give it zero stars if I could. I put my coffee grounds in. As soon as I turned it on, it completely fell apart!

This grinder looks decent, but it barely holds enough coffee beans to make a cup. The charge doesn't last long at all and the grind quality isn't great. It's also difficult to clean so overall this isn't a good purchase. There's plenty of other choices out there and I recommend avoiding this one altogether.

The first thing when I pulled the grinder out of the box, which was wrapped in an unnecessary plastic wrap, was that I unintentionally pressed the power button… and it seems that the button is in a location that I accidentally press often. I don’t know if that is just me or bad design. The grinder came with some charge, and I used the included cord to fully charge it. The indicator light by the USB-C connection is red while charging and green when done. It was charged over an afternoon. An instruction manual is also included, one side in Chinese, and one side in English; the print is small and faint and hard to read. It does indicate the parts and where the beans go. It also explains that a short press of the power button grinds until the coffee beans are all ground, and a long press will grind for three minutes and then stop. The light flashes red when the battery is low. There is no information about cleaning. There is no information about where this is made. On the underside of the bean holder is the dial to adjust the grind. The indicators are arrows toward a smaller dot (finer grind) or a larger dot (coarser grind), and no way to tell how coarse or fine the grind will be—it’s all guesswork and extensive testing. I turned the dial a lot toward finer grind, as finer is my preference, and got an extremely fine grind. I adjusted a few turns toward coarser and saw only a subtle difference. Also, there is a slim silicone ring that fell off, and that apparently was to hold the clear grounds collection piece in place. Since no company information is provided, I have no way to get a replacement and I now have to manually hold it in place or set it on the counter / table. The cylindrical shape is a good design for setting on a level surface while grinding. Because the motor is on top and top-heavy, the surface would need to be level or the unit may tip over. Accordingly, storing the unit upside down would be helpful. For testing, I started with one tablespoon of coffee beans, and the grinder took five minutes to complete. After my grind adjustment, I tested with two tablespoons of beans and the grinder took ten minutes to complete—so allow five minutes per tablespoon of coffee beans. Because the beans bounce a lot while grinding, there are some left when the grinding is done. A nice feature after the grinding finishes is that the grinder pauses and goes the other direction briefly to clear. This has a weaker motor, which accounts for the long grind time, and also means it is not too loud—although it does make some noise. With the long grind time, it is better to put it down than hold it. This can be used for travel if you take extra care to keep the collection piece attached. At home, it is convenient for grinding without having to plug in a larger unit. This can also be used for spices, etc., but again, identifying the coarseness or fineness of the grind is a complication. I love the ceramic grinder, and the battery seems to hold a charge for a long time, but the difficulty of finding your grind coarseness / fineness and the slow speed make this an inconvenient device.
