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

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.

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 have used this grinder for 2 to 3 years and have enjoyed every cup. Robust and flavorful without bitterness. Previous grinder was electric, not a drop through and was a pain to clean. If I didn't clean it, over time I believe I tasted rancid oil and also a bit burnt from the high speed heat. This grinder is very easy to clean I clean it weekly. And no way do I crank fast enough to generate heat. Absolutely no off flavors. My only criticism is that it does get very staticy. I spritz .5gr of water per 30gr of beans, does the trick. But every time I grind I wonder if the original metal base and cup didn't discharge the static inherently.

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.

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.

I really wanted to love it but...there are a few issues that in my option don't make it worth the cost. Lets start with the grind. Yes it is uniform however to get a grind coarse enough for a French press you need to set it to 12-24 clicks which is a large range in grind coarseness and after 13 clicks mine simply comes unthreaded and there are no clicks past 13 so...? And 13 is still borderline to fine to not plug up a press.So maybe I got one that got shorted thread length? meh who knows. Second is the "sticky" base. Yeah not really sticky. I have to exert a decent amount of downward force to keep it stable and I'm not a "small" guy. Additionally there is really no where good to place your hand to exert this force. Then there is the price tag. I have no issue spending good money for a grinder that allows me to grind my coffee to a consistent grind anywhere without electricity and this almost does it but...at this price my antique, literally 1890's antique, grinder that I got at an auction for $50 does equally as good of a job for my application. So it may be a great grinder for espresso grind, I'm not sure not my thing, but in my opinion it falls short for a French press grind enthusiast.
