To preface; I have several hand grinders, too many actually :-) i had initially wanted to add the original Cafesing Orca but I only do pourover coffee so, I only wanted the Ghost Burr. I decided to wait and see if they would release anything with that burr only and thankfully, they did.The Grinder is very well built. It feels solid and there are no creaks, squeaks or rattles and the parts all fit together very well with nice tolerances. The exterior grind adjustment works perfectly and the has a lovely click sound with nice tactile feel. The grinder appears truncated in it's appearance but no worries on that except for the small catch cup. They claim 35gms IIRC but I usually grind 20gms of light roast coffee every day and when ground, that comes close to filling the catch cup. I'd say no more than 22-23gms of most beans will fit. The hopper will hold more though so you must be careful to make sure it will fit in the catch cup before grinding. The grinding experience is similar to other hand grinders. Note that initially, this can be difficult with dense, light roast beans but it becomes easier the more you use it. This is common for hand grinders and not a worry. Cafesing's recommend grind setting of "1-7" is questionable though. I ground initially at 4 and it was right on the boarder of bitter/astringent and when backing off to 5 for the usual V60 brew, that was the ticket. Give a try of the grind setting before you commit to a full dose. In the cup, I have gotten excellent results. To the naked eye, the fines are minimal and I don't get any stalling or over extraction unless I grind too fine, as mentioned above. As far as grounds retention; to say that it has been minimal is an understatement. After a few grinds, I opened it up and honestly, I did not have to. There were just a few grinds to clean out. The scale shows the same; when grinding 20gms, I get 20 out. This is the best result one can ask for. Also note that this, (aside from the Pietro at a radically different price point), is the easiest grinder, hand or electric to disassemble, clean and reassemble. You can literally do it in 5 minutes and it's so easy to do after every grind if you have the inclination and the time. Initially, I could not remove the top nut as it seemed stuck. I contacted Cafesing and their response time was incredibly fast. They asked me for the order number, which I thought was odd but their response was lightening. I was able to rectify the stuck top nut by using some heat from a blow drier so, ultimately, a non-issue to me. The price point of this grinder is outstanding IMO. There are very few hand grinders that you will find that give you a cup as good as this for Pour Over, the Kingrinder K6 being one of them as well as a couple of the Junoesque offerings found here and well as the Timemore C3. Those others are conical burr grinders so this is truly the only flat burr option anywhere near this price point. To get better, you need to spend more money. This is a surprising, total recommendation from me and I did not expect to like it this much or get such good results in the cup or for the grinder to have such excellent functionality. The single criticism is the small catch cup but that is only if you use more than 22-23gms of coffee at time. This is a non-issue for most people using hand grinders but just something to take note of. TL;DR= a total recommendation, especially at the price point. I HTH someone and thank you for reading :-)
