Review: Great fireplace! - This has been a great fireplace for our Lake cabin. We looked at several, read reviews, and then took a chance. We installed it ourselves and from what I heard it was not difficult or time consuming. We did have an issue with the logs, but I don't know if it was our fault or if they weren't shipped. I called customer service and told them they were not in the box and I don't believe we threw them out but perhaps we did. Regardless, they sent me another set and no charge and we had them in about 2 days. This fireplace works fantastic. It heats up the room and it looks beautiful as well. The room we have it in is roughly 800 square feet and you can feel it in every corner. I'm just so happy with everything about it. The great customer service was a bonus!
Review: Waste of Time / money - FYI — DO NOT BUY THIS FIREPLACE!! Customer support of no help - waited on hold for 45 minutes... then when connected - they were clueless to problem. Then hung up on me. Never got unit working... past return date — waste of $700!!

### ⭐⭐⭐⭐⭐ Nice heat, fairly quiet
*by S***. on September 6, 2025*

We bought this to take the chill off in a room that tends to be colder than other parts of the house, and for some back up heat if the electric is out. Works perfectly
