Product review (4 stars): THE COVER BROKE
I came here to find how to get a cover, I hope this one will work, if not I guess i have to install the whole thing, it kept cracking, i kept putting it back on, finally it just shattered into pieces. I have no idea, it's a 10 year old house, if it worked well or not, i guess that means it did.

June 2012, Thanks for the information, I would like this at my present house as the mice get in my dryer vent (the old fashioned kind) HERE! I did not get the comment until after installing a whole new one, but it works great at my old house.
