Its actually the other way around funnily enough.... When the cutting edges of the burr-plates/cones start to become dull, you tend to get a higher proportion of fines or dust in with the overall output. This will result in your machine choking sooner than it used to and the subsequent shots tasting more bitter as these fines result in a higher proportion of over-extracted coffee in the brew.
A visual inspection of the burrs will reveal that the cutting edges start to have a slight rounded appearance to them and if you scrape your thumbnail against them in the direction of cut, the burrs will no longer catch or shave your nail. Burrs in good condition are quite sharp and will easily shave your thumbnail and even cut you if carelessly handled.

. If your technique is sound, you will see benefits in terms of consistency, quietness and longevity. The Compaks are excellent grinders and offer great value (albeit in champagne powder coat at present). All grinders have their particular feature set.
