Once assembled, this is mostly what I wanted. I have  deducted one star for each issue.
1) This replaces a previous unit. That unit had an 18 inch insert where this has 23 inch, but it warmed this room better, with less fan noise.
2) Assembling this unit was delayed while finding a replacement for a too-short bolt. One out of thirteen was a different length. The problem was texted with the required info to the number provided in the instruction booklet, but no reply was ever received.
