The wife has one she uses. I'm assuming it does what she needs it to do. She is the type that won't keep things she doesn't use. And i know she still has hers.
Sorry for the delay. Had to ask wife. She said you apply the mask that comes with the kit. Allow it to dry. Then use the tool to warm up and you massage your face with the warming head of the tool. She says it feels good. Got me. It must be a female thing.
