I recently received this portal window air bar and it is really nice. We use this window air bar in our master bedroom. We turn it on at night to help cool off the room, since the summers will be gone soon and fall weather will be approaching we will not be using our air conditioner so this fan will serve its purpose. It also comes with accessories so if you are someone like me who likes to darken their room with the darkening curtains- this fan is your go-to as it comes with accessories which will help to keep your room dark. This is the best part of this fan- I used to own window fans in the past but I used to hate them as my room would be so bright and shiny as soon as the sun would rise. Buy this fan- you won't regret.
