Negative Positive
Title: Not what I expected
Review: I was not really happy with this. I have the smaller pillow version so I was hopeful about this bigger one. I didnt realize the knobs dont heat up. Also they travel up and down the spine but there is no way to stop them in one spot so you really just get a light superficial massage. The smaller pillow version which has heat is much better. You can focus the massage in any spot.
