This all started when my wife and I went to visit my father in law during a hospital stay. They had given him some medication that made him itch all over. He would repeatedly request we scratch his back. When I went home I made him one of these scratchers and every time we would go to revisit, he would be using it. Even when he returned home it would be right there with him.
I believe this is the best gift you could ever give. The best gifts are the ones that actually get used.
