Entry level grinder, for pressurize baskets only or non-espresso coffee makers. With a low end Krupps it's probably reasonable, as others pointed out on this forum. Price seems OK, if you can settle with substandard performance.
Negative Product Points
If you own a medium to high end machine, it's a waste of time and money. You'd feel 100 bucks well spend when you leave the store, but a week later it's a 100% wasted money, effort and precious beans, you will be on the market again. The grind in setting 3 is just not fine enough, 1 chokes the machine. 2 is still not appropriate, and you ended up with not being able to control your grinds.
Detailed Commentary
I'm evaluating the Infinity for espresso machines. It's the lowest price entry level grinder you will find, thus barley making good crema on my Baratza, if I happen to hit step 2.5 (in between 2 and 3) on the grinder and master the tamp. The grind particle distribution is way to wide, with powder fine and much bigger particles mixed. It leaves a lot of fine powdery residue on the bottom of the cup. It's probably the result of the upper burr only held down by the bean hopper, and being able to move sideways and up and down during operation.
