Product review (4 stars): Love it!
I love it! It definitely has helped keep my room cool during these hot summer days. My vent is right below my window, and my windows could use some updating since air escapes so well. I wish it could extend longer, but its purpose wasn't made for the length I need. Even though 1-2 feet short of legth needed, it has still helped A LOT.
I also have a 2 year old toddler that just loves jumping on it, and it hasn't broke yet! Pretty flexible!
