The Mini Vibrating Massager By Perfect Life Ideas can be used with batteries ( 3x AAA) or the USB port and the cord comes with it. It's a great value and it came very quickly in the mail. It is very powerful considering the size, I have fibromyalgia and it feels so good on my back and joints when I have flare ups. It can be used with some essential oils for a great massage, the 3 nubs on the bottom are designed to fit the body and again is very powerful.Plastic making for a easy to clean surface it's compact and lightweight making for convenience to take with you anywhere or to put away.
