Product review (5 stars): I love this invention
I love this invention! I have a fairly large couch that covers the air vent and it would dramatically affect the climate in my living room. Once I put the extender on I was in love. I bet it will save me on my heating and cooling bill as well. The only down fall is that my robot vacuum cleaner bumps it off the register as its so light weight. I'm going to hold it in place with some bricks. NO biggie!
