Works great. No damage. Very easy to operate. Love that it comes with a remote. We got it for our bedroom so that we can save energy and just run that at nighttime while the main AC is turned off. It is a bit loud, however I love 'background noise' when I sleep so i'm not bothered by it. If you are someone who is bothered by noise while you sleep and you plan on using this for a bedroom, consider a quieter option.
