It was easy to set up. Light weight, and works perfectly. The room is always the temperature I want , especially for extremely hot weather we experience during the summer months. Perfect for keeping my home cool for my newborn. When the room gets hot my daughter develops a rash. This a/c was the perfect solution. Thanks
