We love the look and its heat. Installation was easy. We do find we have a burned off propane smell, but we solved this by having an air purifier next to it, makes us feel its safer that way. The propane industry may tell us all its safe to breathe those off gases, but like now known re natural gas, its better to not have those, so I would always suggest a good gas removing air purifier in the room, just my opinion..
