I purchased this insert for an old wood burning fireplace we can’t use anymore. It looks great! This has multiple brightness levels on the flames and is so easy- everything done by remote control! This is great for an existing fireplace where you can set the unit back and it provides a really nice ambiance. The logs fade in and out or you can have them static and there is a “flame” behind fireplace the logs. My fireplace  is in the dining room of our 115 year old house so I love that I can have just the flames on since we don’t use it for heating. It puts off good heat if you do use it- there is a blower on the front bottom portion where heat comes out.  Great unit and I’m so happy to have “fire” back in my unused fireplace!
