Run away! It breaks those 50$ hardened pins (and loses the pair of 20$ each sperical balls) because the A) casting is damaged at the pivot ball or B) the pivot ball assembly is worn out.
The casting can be fixed for big money in a machine shop. The pivots balls are expensive.
We've got two of them parked awaiting repairs. I replaced with a NH badged Kuhn and couldn't be happier.
