While visiting Ruben, we were pleased to learn they had been using the microwave to heat the rice bag for him but he didn't know how to do it. So we taught him how to do it himself. We showed him how to open the door and how to put the rice bag we made into the microwave. We wrote down the buttons he should push to get the rice bag heated. We helped him get the bag situated on his chair and he said it helps him feel better. We are so happy that the bag helps him feel better.
