Review on ☕️ Enhanced Thermal Insulation Coffee Mug by Thermoserv by Ray Gist

I have used this mug for many years. The last one was at least 13 years old! I decided it was time to replace it. Stores don't sell them anymore. I'm drinking hot tea and need something for the microwave. The size holds the perfect amount for me and still fits in my car cup holder. I tried the new style ceramic mugs but wasn't happy with how quickly the tea cooled. This keeps things hotter for much longer. The lid is tight so nothing leaks.
