Works well but required research to make sure I was using correctly
This is a rather simple back stretcher that includes the stretcher, a thin nylon carry bag, a belt to attach to a chair, and a ball.  While there are minimalist instructions, I found they were not sufficient for me to figure out exactly how to use this (that is, where on my back to put the curve when I was lying down.<br /><br />It is a simple yet sturdy device.  It does require some strength to move the positions of the stretcher and for the initial install. If this is for an elderly or weak person, assistance may be needed.<br /><br />I've done the stretches (2x a day, 5 minutes at a time) for 5 days and I definitely feel the stretch.  It is easier to do now as compared to a few days ago, but I'm not ready yet to move to a deeper stretch.<br /><br />If the instructions were better and did not require my own research, this would be a five star review.
