Product review (5 stars): must be phsycic
I went to my son's house and was talking about how our stove vent went on the blink. He said his did the same thing.  I walked over to the stove looked it over.  I ordered this for my stove hood, thinking how great it would be when it was going to be fixed.  When this arrived in the mail I was going to slip it in the slot and run the exhaust vent When I turned it on the exhaust fan had completely quit.  Plus it was the wrong size but fit his vent space perfectly.  So there you have it!  Hidden memory.  He now has a new vent filter and the stove hood runs perfectly at his house. As for ours the whole stove hood has to be replaced.  At least something got fixed.
