I bought this product and I am happy that I did. Got rid of my stand fan, less clutter on the floor. This fan works great, I love it! I wished it fit better. There's a little gap when I close the window but it still works fine. Iam going to buy the extender coz my window is tall.....I have a slider window. But overall I like this fan, I'm thinking of getting another one. Materials are pretty solid. Ps. I haven't tried the exhaust function to it. If that works, then this fan is the best!!
