I kept the fireplace insert on throughout the holidays and loved it. It instantly creates a cozy atmosphere in the evening, and the flickering logs are unbelievably realistic. My daughter was impressed! We haven't needed the heater yet in Florida, but we are expecting some cold evenings and will definitely use it then. It would be more perfect if it had a longer cord, 10 feet or so, and if the mirror did not reflect light during the day.
