Arrived earlier than I expected. Packaged very well so there wasn't any damage to the Fireplace. Plug it in and it's ready to go. The heat is very warm. You can set it to whatever temperature you want. It shuts off automatically after it heats to the temperature you set it at.  The flames are fantastic! Looks and feels like a real fireplace without the mess and smell. I have not noticed any increase in my electric bill after using this a few months. I would highly recommend this to anyone who wants to bring warmth to your home! Easy to move from room to room, if you want, because it has wheels. Love it!!
