Excelente
Excelente molino por el precio. Muy bueno para empezar adicional el diseño y la estética es muy bien. Lo único malo hasta ahorita es la retención de café, así que hay que darle unos golpecitos para que salga todo el café. Por ejemplo pones 30g de café y salen aprox 28g-29g, con unos golpecitos basta para sacar el café restante.

Worthless piece of junk
I’ve been doing a lot of research on “budget” espresso grinders, debating between getting the fellow opus, encore esp or df54. After quite a bit of research, it became clear that the opus was the worst of the 3 options, although it seemed the difference was minor, especially between the opus and the esp. So when it went on sale for 200$, I figured it was a steal of a deal and that spending an extra 100$ for the esp or df54 was not worth it, was I ever wrong. This grinder is absolutely worthless. First of all, their recommended grind sizes are way off. It says settings 1-2 are for espresso, but I could only pull a shot with setting 4 or above (using the breville bambino plus). This caused me to waste almost half a bag of beans trying to dial it in. If you look on reddit, several people encountered this issue, some saying they couldn’t pull a shot until setting 6. This level on inconsistency between machines is actually amazing, clearly quality control and product testing is low on the priority list for this company. When I finally dialed the grinder for my bean, I used it for two days, pulling 3-4 shots per day, thinking I had it all figured out. On the third day, I go to make my morning espresso and the shot doesn’t pull. Confused, I check the setting to make sure I hadn’t accidentally changed it, but everything was exactly the way it was before. I try again, shot doesn’t pull. Long story short, I spent 30 or so minutes and another half bag of beans trying to re-dial the machine. During this process, the same setting would cause the shot to not pull sometimes, or no oull too quickly with no pressurization the next. Given this level of inconsistency and realizing I’m just wasting my time and coffee trying to make this piece of junk work I gave up and applied for a refund. Secondly, the amount of retention is high and inconsistent. In average I had around 0.5 grams of retention, sometimes up to 1.2 grams, but it varied wildly. I read people recommended to tap on the grinder as its grinding and that everything comes out, but this is false. I’d turn the machine on, tap a few times while it was grinding and again at the end before I removed the cup. Every. single. time. a bunch more espresso would fall out as I was loading the portafilter. Taping, even aggressively, won’t fix the retention issue. I’ve attached a picture of what came out of the grinder after three grinds, and this was with taping during and after grinds. Completely ridiculous. All in all, this is a cheap, inconsistent and messy grinder. Even if I would of payed 80$ for it I would of been disapointed and would of returned it, never mind 200$ (~300$ full price). Save yourself time, money and coffee and get the esp, or better yet the df54. This is easily one of the worst purchases I’ve made in my life.

Very messy
Quality grind, fairly quiet BUT what a mess - the anti static does not work. Spend more time cleaning up than grinding coffee. :-(

Brand new, broken straight out of the box
I heard the quality control on these grinders were bad. But i like the brand so i wanted to just ignore my friends advice. But straight out of the box i got a defective and broken device that doesnt turn on Super disappointing. Ill give it another chance just cause im really forcing myself to want to like this grinder. So ive ordered another and refunded this one. Ill update this review if the next one survives and actually works.... Update : new one came in and works. Button is is a bit finicky. But grids well and looks good.

High Maintenance & getting worse
UPDATE: *** Dropping this to a 1 star. The amount of coffee retention is about 25% per grind after 6 months. I also find myself completely cleaning the whole grinder every single grind. I mean, who wants to completely tear down your grinder every day. Not to mention the mess. There are coffee grinds ALL OVER MY ENTIRE COUNTER each morning. I spend more time cleaning this grinder every pull then I do a shot then my entire morning routine. I give up on this grinder. I have tried week after week, watched hours of YouTube vids...Its crazy. This is by far the single MOST HIGH maintenance appliance I have in my entire house...or have had in like the last 10 years. How did this get signed off by QC within the FELLOW company? Forget everything below, just save yourself time and $$ and go get something else. Don't become another victim of overhyped marketing and under performance. Did my research and thought this was going to be a good choice. I liked the look and multiple reviews from Amazon & YouTube. At first, meaning the first 2 months, the grinder worked great...no complaints, as the grinder ran flawless. It could grind coffee to various coarse ground sizes, NP. But after 2 months I started to notice more and more coffee grind retention in the grinder itself. I would regularly clean like 1x week. My usage was one double espresso a day. So on average, 7 double's a week, again with a weekly cleaning. But after a few months the grind retention would be more and more frequent. Like other reviews, it seemed like every 2 or 3 days, I would have to do a full cleaning just to minimize the retention inside the grinder. I also used a scale and would measure coffee in vs. coffee out. I was losing approx. 2~3 grams per 17~18 gram grind for a double. This is frustrating since I measure my coffee weight to target 17~18 grams depending on my pull. Now, I have to "guess" how much coffee grind retention is going to be trapped in the grinder. I find myself grinding several times to meet the desired weight. It's a guessing game. But to be fair, I dial in my grinder to adjust my pour, I am not sure the average coffee person would care as much. But then again, for this price, I would expect more. The second issue is the anti-static mechanism has seemed to fail. Meaning, now when the coffee grinds come out of the grinder into the small cup at the bottom of the grinder, I have coffee grinds flying everywhere, in and out of the cup. It's like fine dust being blown down into the cup, and flies out onto the surrounding countertop. I have had the grinder now for 7 months with this happening at about month 5 or 6. I can deal with this, as it's more of an annoyance, but that's one of the features I paid for in this grinder. Now I have to wipe down the counter in about a 2 foot radius from the grinder each time of use, due to the fine "mist" of coffee grinds. My last complaint is the conical burr grinder itself inside. Due to the high coffee retention in the grinder, I have to clean out the grinder now every few grinds. Which means I have to remove the conical burr grinder inside. Not that big of a deal but the last few times, the locking mechanism has stuck to the lock position and I could not manually remove the burr grinder. It has a hand twist removal system, but I have to use pliers to twist this off since it was physically stuck. I have already bent the metal latch which your fingers would clasp around to twist using the pliers. I am very concerned that any day the metal latch is going to break, and my burr grinder will be stuck forever inside. Not really sure how to remove it once that happens. If this breaks, I'll go from 2 stars to 1. Overall this grinder seems like a great idea on paper, sleek and modern. I purchased the white color to match my other appliances. Looks good, but functions "iffy". It's high maintenance cleaning with every 2 or 3 grinds due to the coffee retention build up inside the grinder. Even with hitting the sides, shaking the thing, or using the top down "bellow" as I grind, this seems to help a bit, but still lot's of retention. Many people have complained about the coffee retention, some machines seem to do this more than others. The anti-static feature is now non-existent, and my biggest new concern is the conical burr grinder itself is getting more and more difficult to remove to clean. I guess I got unlucky. Would love to try another Fellow Opus Conical Burr Grinder to see if the one I have is a lemon, but I'm not going to gamble another $200 to test that theory.
