Review: Sturdy and does the job - I put this under a bed that really couldn't go anywhere else. But first I accidentally stomped on it really hard (on the extender part). Nothing happened. It didn't even dent. Also, it works. I can feel the air just fine. This is just genius, and well made, even though it doesn't feel like it (it's thin). The magnets stick well. I'm impressed. Worth it.
Review: Great Solution for Vents Under Furniture - This is exactly what we needed! It does a fantastic job redirecting the airflow from under our furniture and pushing it out into the room. In our living room and bedroom, every piece of furniture ends up sitting over a vent, and this has been a must-have solution. The magnetic attachment makes it easy to install and keeps it securely in place. Since adding these, we’ve noticed a big difference in how evenly the rooms heat and cool. Simple idea, but it works great—highly recommended if you have vents blocked by furniture!

### ⭐⭐⭐⭐ Works reasonably well
*by T***R on October 3, 2025*

This does what it is designed to do. It directs the air floor from the vents in the direction we wanted. It can expand and contract. However, the material is pretty flimsy plastic, and there's nothing keeping the two parts together but the fact that they fit inside each other. Also one of the magnets fell off at some point after we'd had it for months. Still, for the price, I can hardly complain.
