We love this fireplace. We previously had a traditional natural gas fireplace that took up a lot of space in our living room - the bricks came out about 3 feet from the wall. When the gas insert had to be replaced, we decided to knock out the old look and bring in the new! This unit is super cool. You can operate it from an app on your phone. You can use the remote or the buttons on the front lower right corner. It has a multitude of color combinations. It has real fire sound (3 volume levels). The 1500 watt heater has both a low and high setting. We couldn't be happier with it.If you follow the instructions and make sure the opening is the right side, it literally slides in, secures to the studs and is ready to go.
