Thank you very much! massager in working condition, I advise all women to buy such for home.

Excellent product. Good quality. Surprised me for not bother to sleep. Summer should be more difficult but in milder temperatures not bother. Fulfills its function in keep the mouth more closed-safe the chin-without hinder breathing. This makes the mouth not stay dry being open. About the size, consider that my head is medium size and fits well.
