Good, odd product for your back
It's very odd to use. The connection in the middle could be smoother. Seems a bit rough to the touch so could be an issue while using. The knobber balls seem to be the same size to me so not much, if any, difference in feel when rubbing your back. My dogs like it when I drag it across their back and sides. Then one wants to chew it. I would recommend the product even though it's a bit difficult to use.
