Powermaster Accumulator
It works just as it should. This unit is slightly larger in diameter but easily installed nonetheless. I"m not sure what goes bad on these things and I'd love to see inside one.

Accumulator Ball
Item shipped quickly, was well packed. It works perfectly, appears to be well made and matches original except its about 3/8" larger in diameter than original. Not a big deal as I wiggled it in there. Overall very happy with the purchase. As always, the team at Highway Stars is awesome!
