For the price that you're paying for all of the features and functions that the Duraflame DFI heater produces, this is an excellent product to bring home and enjoy. We like the fact that you can change the brightness of your projected flames and the rolling effects that you can improve or operate through the remote control that gets provided with your purchase.

The remote may not be the best when it comes to trying to operate the machine. However, it still works for a majority of people, and it always does the job that it was designed to do. One major drawback that a lot of people commented on was the fact that when the blower starts pushing heat out into the room that you're sitting in, it can be a bit loud and disruptive.

Unfortunately, most heaters of this type will experience a louder sound similar to this and if that fact is a deal breaker for you, you'll have to look into higher priced models in order to get a device that doesn't make a lot of noise when it's in the middle of pushing heat into your living space.
