I've had one for a few months. It is definitely well made and durable. No worries there.
I'm disappointed in the amount of pressure applied. If I have a real tight spot sometimes body weight is the way to go. It joins the foam roller and a couple of different sticks and balls as another tool in keeping healthy. Not essential or a miracle worker but a nice addition. In the larger scheme of things it isn't that expensive considering it should last many years.
