My master woman got this for me as an early christma present 6 weeks ago for my extra heavy ball streatcher piece she got about 1/2 half year ago. She say that as now they hang pretty low we must give new look!! She start slow and add some twist every few days. She has worked the screws down a good way. At first pain was big. Balls adjust to pain if left long enough at new setting. On occassion I hear some cruch noises....must mean some curshing happen. I now get to want crusher and ask her for it. She want to get metal bar all screwed down by Spring.....me also.
A real five star in my mind
