## Customer feedback

Customer feedback is strongly positive overall: the supplied aggregate is 4.7 out of 5 from 214 ratings, and the customer summary highlights reported versatility, ease of use and cleaning, and quick cooking. Some customers describe meals taking around 15–17 minutes, but those experiences do not establish a general cooking time. For buyers considering the listed 12 functions and 5.7-litre capacity, the positive feedback is relevant to everyday flexibility, ratings alone do not show how well it suits every recipe or household size.
- Positive themes: Customer feedback reports appreciation for versatility and ease of use.
- Positive themes: The supplied summary mentions positive experiences with cooking results, cleaning and appearance.
