"As you may recall, we recently purchased a HUMIDEX dehumidifier from you. You installed it at your insistence in a location in our home that you thought would be best, although I was not convinced at that time the product could deliver as advertised. This winter has been the wettest and stormiest on the coast in over 45 years, yet I am happy to report that the first morning after our HUMIDEX was installed, OUR WINDOWS WERE COMPLETELY DRY! This is the first time we have had dry windows during the winter in any of the homes we have lived in on the coast. NO MORE BLACK MILDEW, NOT MORE ROTTING WINDOW SILLS! This is the best purchase we have ever made for our home. Thank you."
