The reason for this is in poor quality plastic, to the "German quality brand" Brown (owner is the US company Procter & Gamble) can obstruct in its Chinese plants in both models.

In a few months the assessments will look at this device significantly worse than today. Who does not believe this, please let see the reviews for identical SPI 2200.
