I bought this as a replacement for an expired Russell Hobbs 10934 coffee grinder
. That, despite its many failings, could grind coffee quite finely. This Bodum grinder is much better (and at twice the price, so it should be) but has one major failing: it does not grind very finely, and this seems inherent in its design. It has a feature to prevent the burr grinder being damaged by stones accidentally mixed in with coffee beans. That feature results in the grinder being quite a loose assembly. I'm not an espresso drinker but, grinding for paper filter, I have this grinder set on its finest setting and the grounds are still relatively coarse.
As noted by a reviewer of Bodum Bistro Electric Burr Coffee Grinder - Orange
the instruction leaflet is, to put it mildly, not very helpful. For example, it tells you that the grinder is 'pre-set' to medium grinding, whereas it is only set by inserting the coffee bean container and twisting it (you can only insert the container with the grinder at its coarsest setting). However, once assembled it is quite intuitive to use.
When operating, the grinder grinds quite quickly, the beans flow into the grinder well, and it is no noisier than other burr grinders. But for a grinder where the instructions say it should only be run for 20 seconds before waiting for 5 minutes, the bean container is very over-sized. The seals on both the lids for the bean container and ground container are quite weak, and both come off quite easily. Apart from that the construction seems quite sturdy and solid, and the glass ground container helps to keep static down.
