I have only had the Dimplex insert for a few weeks, but have enjoyed it every night using it without the heat still to warm to use it, but I still am amazed how real the dancing fire and glowing embers look like a real fire, I use to have a real fireplace and believe me this is so much better no messy ashes to clean up or smoke coming in the house from the wind change direction. I absolutely Love this insert, turn on & off with the remote and sit back and enjoy the fire it mesmerizes me. The heater part is very efficient and cozy making the fire even more lifelike. I did use it one chilly night. Very quite. Everyone can't believe it isn't real. I can't say enough about it. I am so glad after lots of comparing inserts I chose this one, again I Love It!.
