EGR Simulator!?!?!?!?

I was on ebay today and found this. Has anybody ever seen this or have any opinions on it. Just though I would throw it out there for some debate. My car has a problem w/ the EGR (keeps throwing codes but the vaccum lines are fine, the valve works, and it is not clogged; so go figure).
