FineLife Quantum Impact Percussion Massager

Star2236 thought this was worth mentioning said

Anybody bought this? How do you like it? I have a couple of protruding disk in my neck and nerves that don’t function right and give me horrible pain horrible pain all over my left side. When I get massages I need them to be super aggressive with me otherwise I can’t feel it bc of all the knots I have.
How does the massager work (meaning does the attachment work by using a vibrating motion?)
Is it worth the money or do you like a pad massager that you sit back against more?
