5.5 Tips for Best Heating Results

• Moisture Content: Foods with higher moisture content heat more effectively. For low-moisture foods, add a small amount of water or sauce.
• Container Contact: The device heats from the bottom. Ensure food or water is in contact with the container bottom to capture heat. For irregularly shaped foods, adding sauce or a few drops of water can assist in steam generation and thorough heating.
• Original Container: For compatibility and best results, use only the original stainless steel container.
• Insulated Bag: Placing the lunch box in the provided insulated bag can help retain heat and improve food warmth.
