I recieved the Rest Secure Dual Control Queen size matress pad and installed it on our bed. I was happy with it but after 5 days one side quit working. Amazon.Com was ready to replace it but it was no longer available and Amazon.Com totally refunded my purchase price and paid for shipping defective product back. I am totally satisfied with the response I received from Amazon.com and will have no problems dealing with Amazon.com in the future. As for the product I have purchased a different one and am very satisfied.Thanks,David Campbell
