I bought this for christmas night for my daughters. They slept with the bedside lamp lit all night! The traditional pilot lights did not light enough. This small pilot is halfway between these two lights. It lights easily by pressing the dog's head, The batteries are standard batteries sold in supermarkets and since I have (they sleep with all night, every day !!!) light has not even weakens! In addition, she is really strong and resistant to falls from the bedside table. I'm really pleased with this product and I recommend it to all parents with children who sleep with a lighted lamp!
