I received my Healthy Wave 5 Therapy Mat about 4 months ago and have to say it was the best purchase I have made in a long time. My Dr. suggested I purchase one for the multiple neurological and muscular problems I have in my back and legs.I was unable to sleep longer than one hour without waking up with pain and spasms.I am now able to sleep for 5 hours straight and am able to fall back sleep immediately. I too have noticed the day long pain in my legs from nerve damage and scar tissue has decreased 85%. I use my mat at least 5 nights a week for 30-45 minutes each session. I also want to mention the great ease in calling the Healthy Wave mat company. A human answers at once every time and answers any questions I may have in a friendly helpful manor. I too had a problem with a part of my mat and within 3 days a replacement was sent to me with the greatest of ease. Thank you so much for your wonderful product and I will be a lifelong customer. Thanks, Adele
