Product review (1 stars): Poor Product, Who The Hell Can't Read A Tape ...
Hay , Let's Climb A Ladder Several Times In The Florida Heat+ Humidity, Lets Bend And Cut  The End Of The Ductwork , Lets Drop Some Tools And Climb Some more , I Mean It's Just A Slip-On 8" Plastic Louver After All , NOT !! How About 7.75 " Then You Can Also Cut The Louver Connector And Smack It On And Hope The Duct Tape Hold's , Poor Product , Who The Hell Can't Read A Tape Measure And Is Making Thousands Of The Wrong Size Louvers ? I Want My Money Back Just For My Time And Labor , Product Sucks !!!!!!!!! JAMES
