I do like the fire crackle sound system and pairs nicely with the electric fireplace that I had bought, also from Wayfair.  The only thing I would have to say about it now, is the cost of the device.  It is pretty pricey, but the electric fireplace (Duraflame Pano Glow) was reasonable, so for around $300, I received both items and I can live with that.  Also, the Fire Crackler Sound System was a lot smaller than expected but has a few choices on the volume of sound.  I am enjoying it.
