Like its peer, it’s engineered to automatically heat or reheat popular food items: pizza, rolls, and even popcorn. Note also its Minute-Plus technology, per which the numbered keys (1-9) each pertain to a set # of minutes. This allows a user to quickly heat foods: 1 for 1 minute, 2 for 2 minutes, etc. Other notable aspects of the Sharp R-220KW include a time-of-day clock, a digital display, and automatic popcorn popping.
