This is a superb single operator neck, back massager. it does the job, and is not bulky or noisy.
I will divide my comments into pros' and cons for this. As an overall rating I think this is great because it gets to spots that you cannot reach yourself. Now while it is nice to have a fill blown massage chair that cannot reach your neck, this can and of course it doesnt take up the same space.  So PRO 1. This is a single person usable device, meaning you dont need anyone else to hold it or position it. I was a little confused with the stirrups initially but as it turns out they are genius.. not only can you position the massager where you want it but you can control how hard the pressure is applied. PRO 2 it is composed of the traditional shiatsu rotating balls that we have all seen, they can go forward - backward or reverse direction and they heat up. Now the heat could be warmer, but thinking thru this if someone ever left this unattended it would not be hot enough to burn or scald so points here warm not hot - good. PRO 3 you can use this on just about any part of your body again you dont need someone to hold it to apply pressure so simple one person operation. The only CON that I can come up with is that the power cord could be a little longer -- this was simply solved by adding an extension cord.  The unit comes with the neck unit as shown in the pictures, a power supply cord that detaches and a cigarette lighter plug cord which for the life of me I dont understand. This is a superb single operator neck, back , massager that I have used. Totally portable and when not in use you can just put it in a drawer, it takes up very little space.  I love it.
