What can I say about this product except I didn’t think it would work.....but it does! I suffer with neck problems and severe headaches but since using this they are significantly reduced. Easy to use, even with s bad shoulder. Would recommend it.
Nice massager. I think that too thick neck will be too small. My neck is thin so everything is fine. Balls themselves are made of soft silicone. I am pleased. Nice massager. I did not know that my neck was so painful). I recommend to buy.
