Build quality. The Mini is built amazingly, really solid. You really feel that you are using a small commercial grade grinder and not some dinky, tinny domestic model. The dosing mechanism is extremely precise and heavy. It's actually quite chunky. When I mention precise I don't mean the dosing is precise I mean the movement of the dosing arms and hopper lever is precise. The finish of this product is also first class.
Negative Product Points
It's only a little thing but I wish the bean hopper had tinted plastic. Light kills coffee freshness and most hoppers have tinted plastic. I also wish the loose grinds tray (at the bottom of the grinder) was more solid like that of the larger Mazzer grinders. I would like it to be made of metal and not plastic. As others before me have mentioned the portafilter fork is a little low.
I bought the Mini a while back to use as a grinder with my Marzocco Linea one group. I previously owned a Rocky which is a great grinder in its own right. Certainly the Mazzer is a better grinder. It is more solid, more durable, heavier grade and looks better. If I was to spend more on a Mazzer or buy a Rocky slightly cheaper I would buy the Mazzer. The grind quality and grind consistency of the Mini is superb, I could notice the difference in grind quality instantly and I've been happy with it ever since. I don't use the dosing clicks to dose but rather I overdose my portafliter and tap it down. I repeat this procedure again and then tamp.
As I mentioned before the PF fork is a little too low and grinds do tend to fly out a little to the left rather than into the PF. But you tend to adapt your style to suit the grinder. One issue I had with the Mini was that when the grinder arrived the bean hopper was marked (light scuffing). The agent who sent me the grinder had a few problems with shipping it so, basically when I finally got the grinder (waited for three weeks) the last thing I wanted to do was ship it back and get the hopper replaced. I guess I could have had this problem fixed but I didn't worry about it.
I would definitely buy this brand again but next time I'll buy a Robur. Slower motor speed and conical burrs, what could be better.
I bought this grinder from Coffee Company. There was a delay in me receiving the grinder but I don't really think it was the agents fault. I was pretty happy with the service although as I mentioned the bean hopper was shipped with a few scratchs on it.
Three Month Followup
I've actually had my mini for almost a year now and I've certainly got very familiar with it. The Mini still continues to be rock solid and perfoms effortlessly. One issue that comes to mind when considering the mini's reliability is that of grinder cleanliness. I have found it necessary to take apart the mini and give it a thorough cleaning (including burr cleaning and vacuuming) once a month. Otherwise stray grounds develop and eventually impede its performance.
