Panasonic Single Function Microwave Oven NE-E22A1 "Microwave Output 3-Stage Switching" & "Linked Cooking" for versatile use "Automatic Heating" with a steam sensor for warming up rice, side dishes, and frozen food with one touch "850W Inverter ★1" & "Frequency-Free" for quick heating ★1 850W Inverter ★1 This microwave oven with 3-stage microwave output and a steam sensor handles both heating and defrosting. Operation has been confirmed. It has been cleaned, so you can use it from the day it arrives. How about it for those who need it for a limited time, such as those living alone, on a single assignment, in a dormitory, or in student life? I have wiped the inside of the oven as much as possible, but there may be some burnt-on stains that are difficult to remove. Please understand.
