I first bought this thing with scepticism.  Errybody done said it wasnt pawerful enuff, so, I gave her a whirl.  Boy was I impressed!!  Not only does it spit out the coldest a/c known to man, it also comes equipped with soothin' ocean sounds to help ya sleep.  I knew from the get go she was the one (besides my wife).  I will definitely give this portable ac unit 5 stars....or 2 thumbs up, and continue to let this product become apart of our lives for many years to come.  Thank ya, god bless, and as my dad always says..."take her easy, and if shes easy take her twice!"
