My brother left his fart machine at my house and wanted me to mail it to him but for less money I bought him a new one instead he was so delighted when he found it on his porch he's been playing with it non-stop ever since it makes 50 different sounds and the volume works real good he gets tons and tons I mean a lot of laughs every time he goes grocery shopping or anywhere out of the house for that matter best gift I ever bought anyone! Very rewarding. Good quality product.
