I just love it when an item is fully assembled out of the box! Installation was just plugging it in! The seven flame setting are really cool and work independently from the heat source. This is why I wanted it- our current fireplace is gas, so no heat-no flame. Sometimes it’s just nice to have the ambient light, so this fireplace is exactly what I wanted. The flame setting allow you to adjust the color; my favorite is 7 which rotates between the primary colors and then blends them- really cool! The heat was tested and works well -it’s currently 100 degrees outside, so I understandably didn’t test it long. I definitely recommend this fireplace!!
