OK, but not for me.
I tried this out and it was just not for me.  There are very brief instructions, so I didn't know about the 3 different heat settings until I was tinkering around with the buttons.  I still am not sure what the colors mean for the heat level - I can guess but there's nothing that actually tells me.  I decided I don't need the vibrations either - they do nothing for me.  Having this option does weigh the back down, even with the magnets in front holding it closed, so it actually does not stay on the back of your neck.  If you want the vibration therapy and some heat on your upper back area, then get this.  If you want heat more on your shoulders, upper back, and neck, and don't care about vibration therapy, then don't get this.  I got the PureRelief Neck & Shoulder heating pad instead, and I like that one better.
