The product meets my expectations and is regularly used. The clean up is easy and especially recommended for use on warm days dringends. For the therapy of the neck and shoulders an orthopedic pillow to all zones in the said areas is recommended to achieve. Requirement in the use of the mat must be a hard and flat support surface. When proceeding to the accompanying description in the duration of individual therapy, a soothing treatment and relaxation, nothing stands in the way. I wish all the other users every success.
