We got our first Advantium back in 2004, replaced it after a power surge in 2014, and upgraded that one with this new model! These are by far the best appliances we have ever used. What I like is that for the past 20 years, the units still have the same great features, but added conveniences (like backlit buttons). Best of all? GE has kept the same mounting hole placement and wall bracket, making it a breeze to replace the old unit with the new one with - without drilling new holes or needing new mounting hardware!
