Review on Automatic Thermostatic Beverage Electric Accessories by Saumeen Shamoon

I ordered this as a gift for my mother and decided to order it for myself and try it before I give it to her. Received it today and tried my first cup of tea and am very happy with the product. It has a nice clean smooth look and is exactly like the photo on the web. The temperature is perfect for me. If you like hot drinks you will be disappointed. I would say it keeps it warm at a constant temperature, but not very hot. I ran to the grocery store and came back and my tea was still the same perfect, very warm temperature. I'm excited. The package contained a blue plastic disc and a pink and white plastic thing whose purpose I don't know. The instructions (which are very minimal) don't mention anything about it, so I have no idea what to do with it?
