I think it's appropriate. The audience of Beyikang IF electrotherapy instrument is originally middle-aged and elderly people. It is much better to give the electrotherapy instrument as a gift to the elderly than to send a meal or something. It can preserve health and make the body healthier. Old people like it very much. The current and voltage of Beiyikang medium frequency electrotherapy instrument are constant and controlled in a safe range. All the old people in our family use it, and their parents often cook with fire. After using this electrotherapy instrument, the fatigue of the body has also eased a lot, so you can use it with confidence. My mother is 78 years old this year. Before, it was lumbar process, and people with periarthritis of shoulder had poor blood circulation and sometimes edema. She often says it hurts here and there. Before that, she was sent to the hospital for physical therapy. The doctor used the intermediate frequency therapeutic instrument of Bei Yikang, which was very good. I went to the hospital several times, and the cost of going to the hospital was quite high, hundreds of dollars. Later, I bought one at their house, and the symptoms were much better and relieved in a few days. I also bought one for my aunt. This is a perfect gift. Old people will like it very much.
