“I purchased this massager solely for the wireless function. I have only had those before that required to be plugged into an outlet. I did not expect it to be such good quality in softness and comfort. The neck massagers are intense and you can pull the cable around your neck to add pressure. I suffer from migraines and this has helped with relieving them. It works I would say for up to an hour after charging, maybe longer since I have not used it longer than an hour. I love that it shuts off on its own after like 15 minutes of use. There are different modes including one for just vibration. Get one and enjoy, great price and great function.”
