From the first day to the present, every time we brew coffee with this product it is somehow burning the plastic and emitting what we believe to be unsafe or harmful vapors. From the kitchen throughout the entire house you can easily smell the plastic being singed. It has not caught on fire as of yet, but with the apparent flaw in design we believe it could be possible. I have also found if you lift the lid up you can pour faster and will not spill coffee everywhere. However an in-home product should not have to be used outside to ensure the safety of the family.
