Read all review and decided to give this ac unit a try.  I am so glad I did!  It is powerful, efficient, and cools like a dream!!!  I do not find any significant noise while operating and absolutely love this product!!  Wish there was a local retailer to purchase accessories - AND WISH THE CORD WAS AT LEAST TWICE AS LONG!!  I don’t have very many plug ins close to windows - other than that THIS IS A GREAT PRODUCT!!!
