The week this arrived at our house, we had our first very warm, humid weekend of the season. My husband had this Newair Portable Air Conditioner set up in about 10 minutes. It was so easy. I think the part that took the longest was actually getting it out of the box because it's kind of awkward. While I read through the directions to make sure I wasn't going to accidentally break something, the user settings are basically self-explanatory. It's very easy to use. It quickly cools the space and it isn't absurdly loud (much quieter than a traditional window unit but not as quiet as the central air in our previous home). *I received this product in exchange for a review on my website, but all opinions are my own.*
