The IonMug with Charging Coaster is the perfect way to keep beverages hot all day. I love that I no longer have coffee, tea and hot chocolate that would get cold in an hour. The lid slides to close both openings and is helpful for avoiding spills. I love that I can take this to work and plug it in for hot beverages anytime. I received a free sample from home tester club in order to test and review while providing my own honest thoughts and opinions.
