ROK GrinderGC Manual Coffee Grinder - Portable Stainless Steel Conical Burr Grinder with Adjustable Settings for Smooth Grinding, Ideal for Espresso, Travel & Camping - Silver

1st ROK grinder purchased while posted to Germany. Worked great with one coffee bean spitting out of open hopper every time. Wife took that one still working perfectly. Second arrived with a loose part in gears that caused plastic geRs to break off. Manufacturer replaced it immediately, within a week. This third hand grinder works perfectly adjusting easily from espresso grind to drip grind for visiting relatives grinding light roast and medium roast Ethiopian beans and Mexico organic. The handle was not rolling to easily but that was fixed with a spray of silicone lubricant and now turn much more easily. I would strongly recommend purchasing. Kinda pricey but works on light roast where my old hand grinder struggled.

It’s cool. Grinds are espresso quality although you don’t have much variation in that range. Real issue I had was when at the finest setting you are cranking for over a min. Also it be cool if the gears weren’t plastic…. A wood v base would make this a statement piece and almost worth the hastel. All the plastic makes the price to high. Prob better off spending more for a flat burr… but for what it is I’d say it’s cool.

Like other reviews. Unstable, lots of plastic, hard to adjust. Produced a nice grind, though. Should have purchased something else.

I did considerable research on different grinder options for espresso makers on a budget. It wasn’t an easy choice for me, since “beginner” espresso grinders are still formidably expensive. I chose this based on the reviews I both read and watched online. While I’m still learning how to dial in my espresso, I am still very pleased with my purchase. It gives me the quality and the adjustability I have sought.

I received my ROK grinder in the mail, today. Everything arrived assembled except for the handle. Once I got it set up and began the first grind of 16 grams of beans, I immediately began pulling the grinder off of the counter. It is so light and made the grinder feel like a toy I might break.That said, It was very easy to set for espresso, only took 3 tries from 0 and for me that is exceptional. Grind quality is fantastic at this size. I have not tried it on larger grinds yet. I purchased this as my backup grinder, as my electric one had to be repaired. I would recommend this if you are unable to spend more on a grinder or if you want one that can be used without electricity.

The design of the grinder is VERY nice, unfortunately only on the first view.If one looks further, they used cheap plastic, the base looks like cast iron but is from plastic too.The grinder when one is grinding, is VERY unstable.The grinder is not clicking correctly from the first minute on but I have to say that the grinded coffee is very nice.If they charge $50 US for this grinder - that could be a reasonable price tag.

Two days after I recieved the ROK grinder, i got rid of the Rossi commercial grinder I had been using for seven years. I only brew espresso, but I drink six or seven cups on a normal day. I brew single shots, not doubles. It takes under thirty seconds to grind about seven and a half grams of coffee. The grind is perfect, with minimum dust. The ROK is much quieter than my old unit and the slow speed of the grinding does not heat up the grounds prior to loading. If you add a couple of drops of water to the beans before grinding, static is non-existant. I made a plastic cover for the grind chamber, so none of the beans are kicked out while you are turning the crank. My prep area stays much cleaner now.The ROK is well made and looks great on the counter. I need to put my hand on top of it to keep it stable while grinding, but it's much easier than wrestling with a hand held manual grinder.If I was preparing coffee for multiple people or needed to grind for french press and drip as well as espresso, I'd probably want to have an electric grinder available, but for an individual whose coffee preferences are stable, the ROK grinder merits serious consideration.

This is the grinder I learned to make espresso on and I can't see myself ever replacing it with an electric grinder. I only make up to two espressos a day so the additional cost seems like overkill. The quality of grind and flavor is fantastic from the ROK, but it could certainly benefit from a stepless adjustment method. The central drive shaft can make loading beans from the cup a bit weird, and it would have been great to have a dosing cup that fit a portafilter. I think with a V3 they could taper the output to fit a narrower cup and add some kind of agitating mechanism after the burs to sweep the walls for better retention.
