It is amazing how just a little air can help start a fire. When I put batteries in this, I was at first disappointed by the low volume of air. I was expecting airflow like a blow dryer. But when I tried it, I was instantly wowed. It took 30 seconds to make a wood fire blaze with one match. The gentle air flow is just right. It doesn’t stir up ashes, but gets the right amount of air to the fire. I’ve used it many times since and had the same experience each time.
