This is a great alternative. It works well and can work with different parts of your body. I was able to get the unit move up and down my entire back with adjusting my hand position. Took a bit of time to gain control to but you will get the hang of it. The adjustable level comes in handy as I wanted it to be softer when using it around the neck area and can increase the strength for lower back.
It would be great if the unit came with a longer electrical cord, but that is a easy fix with an extension cord.
