The heater arrived Friday afternoon and there was damage to a cover so it's being replaced Tuesday with a replacement and the customer service so far has been excellent and I will follow up when the unit is swapped.

Very nice product!
This is a replacement for an 8 year old similar product. It was super easy to install and much more light weight than I anticipated.
