I bought this product in May, I have not received the product yet, and they do not respond any of my emails about the status. Think twice before ordering from this company.

No instructions or manual ?

I bought a new sealed unit from Amazon and the heater did not come with any instructions on how to adjust settings and use features. It’s disappointing
