This is a piece of junk
I bought this to replace a similar model I'd had for about 15 years and finally developed a crack that dried out the lotion. That was a  little over a year ago. It worked ok for about 6 months then started coming apart - the rolling balls started popping out, it came loose from the handle, the head unscrewed itself. I finally completely gave up on it today when it wouldn't stay together at all. There are many other similar models - this one is not worth the money.
