Bests & Worsts Reviews from Amazon

All I can say is WOW! I've got 4 ruptured discs in my neck, C3 to T1, and usually the chiropractor is the only one who can dig into the muscles in my neck to get them to relax. Not any more! Is it uncomfortable? Very. Are the white balls on it hard? Extremely. But releasing the tension in those muscles takes some force. So prepare yourself by knowing that they are hard and unforgiving, because otherwise they wouldn't work. After a few minutes all the tension is gone. The muscles in my neck are so tight, I can hardly turn my head. After a few minutes on this thing, they loosened up and my pain was significantly less. If you turn your head a quarter inch to the side while on this, it will put extra pressure on that side and help to penetrate those muscles even more. I'm pretty sure that it you just have a stuff neck, it might not give as much relief as a regular massage, but if you've got ruptured discs like I do, the pain relief and the range of motion you get back is unbelievable. If your neck and shoulders hurt, don't wonder if you should order this. Do yourself a favor and just buy it now.
