It is durable and has good quality. It is only for the neck. Personally, I have issues with my neck, such as alignment and tight muscles, which cause headaches and stiffness. I was hoping that the device would help me, but it didn't do anything for my problem. After 5 minutes of use, I initially felt pain, even at low intensity, and within a short time, I started getting a headache. Maybe it works for people who don't have a major issue and just want relaxation. However, my father also tried it and experienced pain in both his neck and lower back, where he has issues. Be careful when buying something without knowing if it is suitable for your problem.
