Product review (5 stars): Works Exactly as Described!
After reading the reviews, I was skeptical about this product but took the plunge and ordered it because we recently bought a condo that has window placements that make it impossible to arrange furniture without covering a heating vent. After a spell of cold weather, it became clear that either the sofa would have to be moved (this meant relocating all the cable hookups also) or something was going to have to be done to deflect the warm air out from under it. It fits right over our vent and doesn't show at all under the sofa. Best of all it works! Granted, it is fairly flimsy plastic but since it is also supposed to be used under furniture, that is not an issue with me. It is also probably overpriced but it certainly didn't break the bank and the thing solved our problem. The air is now directed out into the room instead of up under the sofa.
