I'm back to a 5 star review: finally the 3rd insert has continued to stay working!!!! Thank you for the excellent customer service in sticking with me until I was able to obtain a working insert.  I had to previously change my review to a 2 star since I'm on my 3rd insert due to it overheating and turning off after about 3 minutes with error code. Company has been great to work with, but not confident the $650 electric fireplace will ever stay running. Flame ambiance is a 5 star as well as the outer cabinet, but not much good if it won't help heat our cabin's front vaulted ceiling room every winter. HELP not sure what to do.
