"I take my dog to work everyday and she rides in a Kennel Cab (plastic sided kennel). This fan helps her get a bit more air-flow in her kennel. It is extremely quiet; quieter than an electric toothbrush and no louder than a computer fan. It's not super powerful, but it helps keep her a bit cooler in the hot summer. I love the fan, I only with it came with the AC/DC adapter."
