Really disappointed:( Thought I could try the product, and if not satisfied with the advertised satisfaction or your money back guarantee & 24 hour customer support I would be ok to get a refund, but experience was poor, no customer service and only option to post item myself back to China for it to then be examined and a decision made whether they will refund me. Awful service, and I’ve lost a lot of money now for a product that hurts me, not relaxes me
