Don't buy this grinder if you are serious about quality.
Positive Product Points
The grinder looks nice and is affordable. I also liked the blue LED that indicates that the grinder is active (if you are deaf).
Negative Product Points
The first grinder broke after a few months. Krups sent a new grinder under warranty. This machine broke again after 6 months of casual use. The GVX1 does not grind fine enough for espresso machines. I could make borderline OK shots by applying lots of pressure when tapping.
Detailed Commentary
It seems like the motor of this grinder is not overload-protected. What apparently happened with both machines is that a bean got stuck in the mechanism, slowing down the motor until it overheated and burned out. The grind grade selector has 17 positions which seems to imply that all fineness grades can be produced with this machine. However, even in the espresso position, the grind was never fine enough to fully qualify for espresso. I could not find an adjustment mechanism inside the machine that would correct this limitation. As to noise: The grinder emits considerable noise, both under load and when spinning with no load. This is probably to be expected from a low-price machine. The hopper and collector bin are made of flimsy plastic material and collect lots of electrostatic charge during the grinding process. Both noise and low-cost construction could easily be tolerated if the grinder lasted more than a few months.
