Works well.  Unfortunately, an invasive species of insect crawled inside and has laid eggs, so even though it has been brought inside our home during winter, insects continue to hatch and crawl out inside the storage closet!  I am grossed out and don’t want to install it back in my bedroom in the summer.  I may purchase a portable unit from Wayfair in the Spring so no insects can crawl in from outdoors as long as our screens stay in place, which cannot happen with window air conditioners.
