Replaced two units (40 years old). Did not think I would be able to find. Minor issue with installation, moreso with the house than the product. Will look to purchase a third.

Glad they had this hard to find item. Was a direct match for what I was replacing. Item was exactly as advertised, well packed and arrived on time.
