Product review (4 stars): old blower wheel wobbled out
the old blower wheel wobbled out and the new one has a perfect flat where it's supposed to be.  My only downgrade is because they provide the clamp, but not the clip in the package.  Thankfully I had some here (1/2") and easily replaced it.  I was more work taking out all the screws around the blower cage than actually replacing the blower wheel itself.  Well worth it.
