Used a few times. The structure prevents direct contact, and warm air gently flows out, providing a soft warmth that's safe for small children. The water inside is the perfect lukewarm temperature the next day, so you can use it to wash your face or do dishes, making it eco-friendly＾＾ Please refrain from purchasing if you are concerned as it has been stored at home. No dedicated cover. I am unable to offer a discount due to shipping costs.
