Disadvantages:
- Identical seen at Edeka for 20,00 Euro (instead of 30 euros for the stock at Amazon)
- Pedal barefoot to contact not good (too narrow), you should wear a shoe with a hard sole. Suggestion: foot pedal.
- Another suggestion: Red water level indicator on only one side, both sides would be better. Could also increase linearly (increases only after a certain capacity at all on).
