Looks like a great find Paul! Looks real similar to one I got at the auto parts place (Can't recall if it was AutoZone, Checkers or Napa). I think mine swivels too from left to right. Was under $5. Funny, I tried a small round and then a large round just like "Maxiview" shows in their ad, but liked the rectangle the best.

I tried different corners, but found I liked it in lower right corner the best.

I originally had one on passenger side also, but didn't like it. Now that I'm used to it, I may put pass back on.
