Thank you for your review and for your feedback. We are very sorry to hear about your experience. Our Adapter insulating ring uses the generated heat more effectively. We suggest after preheating to manually control the temperature and time settings for more precise results. Set your target temperature, adjust using the “+” or “–” icons. Then set your timer, once the temperature is set, use the “+” or “–” icons to set your desired cooking time. Our Precision Induction Multi-Cooker flexibility allows you to better tailor the cooking environment to your needs. If you have any questions, please feel free to contact our Support Center.
