I got one at Menards for 12.99. Suppose to keep beverages hot or cold for many hours. Its does!!!!! Poured hot water (150 degrees) into it and after 4 hours it was still 135. Last nite I filled with ice at 7:30 pm. This morning at 9am still half full of ice. Now after 18 hours still half full of ice. Fully expecting ice will be there after 24 hours as the TV commercial says. Made of stainless steel and holds 32oz. 3 different methods to use the top. Straw, sip or pour.
