This product is not designed to push air like a traditional fan, which may not be immediately obvious. It works by utilizing heat from the surface it sits on, to generate energy and move the blades.Initially, I tried using an electric fan behind it to enhance airflow, but it proved unnecessary. Patience is key; over time, you'll notice its efficiency in evenly dispersing heat. I use it in my sunroom, placing it on a kerosene heaterTwo key observations:1. Without it, the sunroom feels warm from the waist up but cold below. With it, the heat is evenly distributed.2. The quality of heat from the kerosene heater, enhanced by this product, feels different and more pleasant compared to my central propane heating.The item is well-made, aesthetically pleasing, and effective. The only improvement would be a more ergonomic handle for ease of use.5 stars with no hesitation.
