I highly recommend this coffee grinder, if you're an average coffee drinker and do not want to spend much money for a high-end device. We use a coffee percolator (Caffettiera) and a portafilter espresso machine and grind for our espresso beans in this mill. For both purposes, I think it is definitely suitable. On the finest grinding stage of Espresso is even too fine for Siebträgermaschine. Who has a very high Siebträgermaschine that works with more pressure, probably needs finer powder than it can deliver this mill here. Because I would then search again exactly beforehand. Of course you can not expect a top device for that price. The powder is by no means ground as evenly as it should be perfectly legally. The mill is very noisy. If our daughter does nap, we can not turn it. But I would buy it again because it meets our (average) requirements.
