Looks legit. Bet that is a pretty decent rolling ball. Wonder how much that ball will go up to. You know how some people on Ebay with stuff this is a little out of the ordinary.
On a side note: There is guy in my mens league that uses a regular Sidewinder in OOB condition as his spare ball. At first I was like what the hell?
But, it works ok for him because it burns up just past the arrows. I hate bowling on the same pair as his team though. Him and two other guys on his team throw particle balls....and there isn't much head oil to begin with, and they just tear is apart.
