Mini-Slim PRO Coffee Grinder

If you are looking for a portable, manual coffee grinder that offers consistent results, this is the one to get. There is some minor paint chipping after extensive use, but this doesn't bother me much. However, be prepared for a morning arm workout.

Hi! I'm fairly new to the specialty coffee scene, but having this be my second hand-grinder (and the one I'm still using) I'll give my thoughts. I've been using this hand grinder daily usually one cup of coffee a day since the beginning of the year. Pros: 1. Shape and size: very easy to grip, holds up to about 30g of beans in the hopper while the lower chamber on the "Mini Slim Pro" model will comfortably hold over 60g (haven't tried more). The opening of the hopper is wide enough to pour beans into without spilling too! 2. Materials: The metal hopper and bin feel really sturdy, no noticeable scratches so far and it feels like it will last forever 3. The Handle: super sturdy, I think it's cast aluminum and will never bend on you. 4. Decent grind quality: This will not be as good as the $230 Comandante or other very high-end hand grinders, but for drip coffee, Aeropress (my method of choice), and pour over (I've tried Kalita Wave 185) this grinder will make tasty coffee! 5. Burrs: Made of ceramic, I haven't had any problems with them.\ 6. Noise: this thing is much quiter than any electrical appliance with a motor, great for not waking up roomates! Cons: 1. The latching mechanism: Instead of threads, Hario went with a simple latch that makes it easy to attach and remove the bin from the hopper - if it's facing the right way. It's a small annoyance, but if I remove the grounds bin to pour my freshly ground coffee in my Aeropress and the hopper isn't facing the right way, I have to hunt around the side of both pieces to make sure the little latch is aligned. 2. The latching mechanism: so this isn't actually a big problem - yes the latching mechanism does wear a little bit on the "hopper side" of the grinder, as you can see in the picture. Most of that wear occured within the first month or two, and now I've had it for over 5 months now and it hasn't progressed. If you're worried about wear, just grip the grinder a little higher and support the hopper a little more. However I do feel this issue was overlooked in the design. 3. Grinder Consistency at coarser grind: So for a <$100 grinder, the consistency I believe is pretty good, but if you're grinding for french press, filter, or cold brew you're gonna have a decent amount of fines, which are smaller particles/dust than what you're aiming to achieve. For Aeropress and French Press this doesn't matter too much (you'll still get great coffee as long as your beans are also good) but these fines do have a tendency to clog paper filters, such as for pourover (not as bad if you're only making a couple cups) and for cold brew. I ground 90g of coffee coarsely to make some cold brew yesterday for the first time, and I thought I'd filter the coffee through my Kalita wave, but yeah that didn't work out very well, the whole thing clogged up. I had to use my aeropress to pressure-filter the coffee! 4. Setting the coarseness: if you've never used one of these before, trying to figure out exactly how many clicks to set the grinder to the first time is intimidating and confusing! Just remember: 10 clicks from completely closed is medium/drip, 5 would be fine/espresso, and 14 is about as coarse as you want for french press/cold brew (I brew french press at 12 clicks). This website is also super helpful: https://honestcoffeeguide.com/guides/coffee-grind-size-chart/ (the mini-mill chart also works for this) 5. Effort: Yes this takes some elbow grease. Apparently much more expensive hand grinders have bearings and sharp metal burrs to make it a lot easier and smoother, but this isn't that fancy (or as expensive) 6. While slim and portable, it doesn't fit inside my aeropress like the aergrind might. I wish there was a slightly easier way to carry it for travel, but this is more of a nitpick than a real concern. As you can see, most of my cons are more nitpicks and annoyances, but in reality, are very easy to deal with day to day. Experience: The grind quality of this may not be too terribly much better than the "plus" model or other grinders out there, but I really enjoy the metal body and large grinds bin this grinder has. For a hand grinder below $100 I am very happy with this purchase! It takes a couple minutes to grind the 17g of coffee for my cup in the morning, but it's always much less time than it takes for the kettle to heat up. Over 30g of coffee though and you'll have to refill the hopper, and by then the churning of the handle starts to get old (the 90g of coffee for the cold brew yesterday took ages!). Also, pourover brewing will probably take a little longer than some instructions say due to the filter beginning to clog a little near the end of the brew, but it's not that big of a deal and your coffee will still taste really good! (and sometimes excellent!) I usually go with aeropress (at a medium-coarse grind) and I get a consistently tasty cup :)

I went with the Hario Mini-Slim Pro after doing a lot of research into electric grinders and being unsatisfied at not being able to find a clear winner at the $130 - $150 price range. The $60 I spent on this grinder is worth every penny and, in retrospect, an electric grinder would've been overkill. I'm a light coffee drinker, so I'll only have two to three cups a day and around the same time; so filling this little guy to capacity and combining the grounds with my French Press gets me what I need. No real complaints, other than a suggestion to very closely read the instructions before using the grinder to make sure that you set it correctly, know how to clean it, and understand how not to break it. I'd recommend the Hario Mini-Slim for anyone who needs a coarse grind and doesn't drink a ton of coffee each day.

I have been using the the Hario Plastic grinder for 3 years and I thought I need to updte! This product is a metal version of a plastic Hario Ceramic Coffee Mill with 3 times higher sticker price. However, all of the good things about the original product are negatively effected. Cons: - Its heavier - 3X more expensive - The container locking mechanism is is weak and it opens up without your intention. Its a design flaw cause by charging the design that was already working. - the metal surfaces are slippery in comparison to the plastic one and not easy to use for a product that needs to be mechanically operated. - every time you open and lock the mechanism some of the metal and paint surfaces would grind into your coffee and contaminates it. 4- The customer service was not helpful in addressing my problems. They sent me another container thinking that the replacement of the lower piece would solve the issue of container opening up randomly, but it did not. Pros: the grinding handle is a better quality Conclusion: Don't buy the over-priced metal one and just buy the basic plastic Hario.

I'd been having trouble finding a good quality hand grinder, but this delivers. I swapped it for my GSI camping burr grinder at work because the lever is longer and more comfortable for large grinds. The connection of the crank to the shaft isn't superb, but it's decent, and the the grinding action is nice and smooth. All in all it's a solid nonelectric burr grinder for portable and general use.

Overall, I am quite disappointed with this grinder. Pros: It does a nice job of grinding and making consistent grounds, and the upper section seems to all be well designed and works quite nicely. I bought it because other reviews stated it paired nicely with an Aeropress, which I must say, is true with respect to consistent grind quality, and fitting into aeropress for transferring grounds. IF I was buying for the top section only, I would say grinder is quite easily worth the price, BUT... Cons: The bottom section which catches your grinds becomes detached very easily while you are trying to grind, as is noted in many other reviews. I had read these before purchasing and thought it wouldn't be a big deal, however after several months using the grinder at least twice a week (time prohibitive, and I am too lazy to get up early enough to grind and aeropress my coffee) this is becoming a serious deal breaker. It makes grinding enough beans for a couple of cups of coffee much more difficult as you are constantly futzing around with the bottom portion trying to keep it attached to the grinding apparatus and not lose all of your grounds, and it seems you could often use a third hand. Also as noted in other reviews, the mechanism to keep the two pieces joined is VERY EASILY advanced beyond the distance which the dimpled in metal on the bottom portion is supposed to slide into the metal groove of the top section. This is made worse as the grinder comes apart very easily when you start grinding with the correctly connected top and bottom pieces, as it constantly tries to separate top and bottom portions while you are grinding, it is then difficult not to advance the dimple beyond the end of the groove as you try to put it back together and keep grinding. Overall I am very disappointed for the price of the product, especially by the fact that no self respecting engineer could pretend to be happy with the attachment system, and it appears to be an attempt to cut corners to save costs. I will try to attach some pics when I can.

I've been fairly disappointed in this grinder. People who commented before pointing out that it's worse than Plus model were right. Specifically, this model has a number of engineering and manufacturing issues. The grinder is hard to dial in and will have a ring of scratches around the edge of the bin (silver on black) - you will not be able to avoid those scratches, it's a design flaw, see below. First, everything rattles and wobbles. Every single joint has massive allowances. I had Hario grinder before (Skerton Plus) so certain stability issues were not unexpected, but in this 3rd generation I hoped I wouldn't need to put duct tape on the axis. Alas. Hario fixed the outer burr stabilization issue by putting a silicone gasket around it - that effectively replaces half of the popular "duct tape hack", but the fit around the axis is still bad. The axis is held in place in 2 points, both above the burr - that's one problem. The second problem is how it is held - with fairly thin washers. One could have called them simple bearings, but they have the thickness of a washer and a hole significantly larger than the axis. This results in a lot of freedom of angular movement. I couldn't detect any asymmetry in the central burr, but it still scrapes the outer burr unevenly on fine settings. Second, the fit of the ground coffee bin and the black paint... This is engineering sacrificed to design - and sacrificed in vain, I must say. The bottom part overlaps with the top part. There is a ring of unpainted steel at the bottom of the top part - this is good because that area gets scratched a lot when you attach the bottom part. That's where good news end. The bottom part goes higher than that ring, which means it will scratch the paint. The paint will be damaged even after a couple of uses, regardless of how careful you are - read further why. It's possible Hario attempted to fix the problem with scratching by introducing a gap, the inner diameter of the bin is much larger than the top part... or maybe it's just another fit problem. That doesn't eliminate the scratching, but may reduce it at the cost of the bin moving in your hands as you grind. That's bad usability. But that's not all. Look at the locking indent - it's located only on one side! So you are guaranteed to scratch the opposite side of the grinder as you lock in the bin, in particular if you try to achieve some sort of a solid lock. To work around this I had to put a few pieces of electrical tape on the outside of the top part, when the bin is attached, the tape works as a spacer. Finally, somewhat of a nitpick, when you move the adjustment wheel, it is free to wiggle between the clicks - there's nothing holding it. This could have been avoided if they used recesses in the base the wheel turns on top of vs. extrusions on the wheel clicking against extrusions on the base. You can see better design in more expensive hand grinders. Pros: The handle feels great, not too heavy, but stays in place as I grind. Uniformly transfers the torque to the axis.

Perfect everyday grinder! It’s particularly great for those who are only making 1-2 cups of coffee.

Bought for camping. Broke after about 10 times using, the inner grinder compartment spins with the handle instead of grinding the beans. At the price point expected this to last and doesn’t seem to be able to return through Amazon. Disappointing.

Das Mahlwerk ist top. Die Maschine ist leichtgängig und der gemahlenem Kaffee hat eine gute Körnung. Ich würde die Mühle nur für 1-2 Tassen verwenden, sonst bricht einem der Arm beim Mahlen ab. Problematisch ist die Verbindung zwischen dem Ober- und Unterteil der Mühle. Beide Blechteile werden "nur" über eine ins Blech geprägte Nase/Nut verriegelt und das hält nicht wirklich gut. Folglich muss man die Mühle beim Mahlen am Oberteil greifen. Bei mir funktioniert das ohne Probleme. Meine Frau hat aber kleinere Hände und tut sich schwer damit die Mühle oben zu umgreifen.

Recommandé par les torréfacteurs, ce petit moulin manuel est effectivement très satisfaisant. Maniable et robuste, la mouture est bien adaptée aux cafetières à filtre. Il est réglable, dans une mesure cependant un peu restreinte. Son contenant le limite cependant à 4 ou 5 tasses. Au-delà, il suffit de vider le bac et remplir la trémie. Mais le processus est alors un peu long. Un moulin plus adapté aux petites coulées, peu fréquentes. Toutefois cette étape de la mouture à la main participe au rituel antique d’un bon café : l’attente, l’odeur et la discussion qui précèdent la dégustation, l’amplifient. Pour lors, après presque un an d’usage, il résiste bien.

Muele muy bien el café, pero a medida que mueles, se abre la tapa transparente, el cierre del depósito, se pasa de rosca ya que son unas endiduras que no aguantan bien, la pintura se desgasta enseguida donde roza con el depósito. No lo compraría de saber que esta tan mal diseñada... con que hubiesen puesto otros cierres funcionaría genial, además el tamaño y la maneta están muy bien. Si la llevas de viaje se desmonta por todos lados.

Un grinder di ottima fattura! Leggero, facile da pulire e tiene benissimo in fase di macinatura! Acquisto perfetto per le mie esigenze.
