All excited when opening my package. Completely shocked to find the rubber, plastic inside the kettle. The advertisement on Amazon says it is BPA free, really? I can never understand why we need that piece of plastic inside the kettle..... The whole point of me buying stainless steel kettle is to be free from plastic or rubber and first impression is really shocking. I really am not sure what to do.... To use or not to use? And the hazardous material of the thermostat were simply making me anxious. God knows what is in contact with the water.
