Hi Washington, thank you for your feedback on the Winco mini muffin pan. We're sorry to hear about your experience with the cup design depth and especially the coating issues you encountered. It's particularly concerning that the non-stick coating started coming off during the first use in your commercial dishwasher, and we understand how frustrating it must be to deal with a plugged dishwasher as a result. Commercial dishwashers can be more aggressive than residential units, and coating durability in that environment is crucial for professional kitchens. We appreciate you taking the time to share these details about both the design expectations and the coating performance issues, as this helps us understand how these pans hold up in commercial applications.
