Product review (5 stars): Like Tony the Tiger would say "Their Great!"
Got these when my son was moving out of his apartment from college.  After reading the cleaning rules, I decided there was no way you could ever get them cleaned good enough without having them charge your for them.  What the apartment managers wanted for a set of four was outrageous!

I cam to Amazon and found these.  They were reasonably priced, fit perfectly, and were easy to install.  If you have older reflector bowls that you can't seem to get clean anymore.
So really there's not much more to say.  This product fit its expectation exactly as it was suppose to.
