## Customer Reviews

### ⭐⭐⭐⭐⭐ expensive but, really, the only option for 14" wide vents
*by F***T on July 6, 2025*

Yes, it costs more than you want to pay.Yes, it does exactly what you need, because all of the others are just too small.this fits 14" wide vents just as perfectly as you hope it does, and yes, the magnets are as strong as you want them to be.

### ⭐⭐⭐⭐⭐ Awesome! UPDATE:  I bought a second.
*by S***C on June 7, 2024*

Great product. YES, much more expensive than the other options on Amazon, but..... It's made of strong acrylic so NO melting plastic like the reviews from other cheaper venders. We needed the full 13" width and the full 38" depth for our oversized loveseat. Magnets are strong and instructions are simple to follow.Super happy.UPDATE: This is the only thing available that is wide enough and sturdy enough to survive the cold A/C air flow and the hotter, winter heated air flow. The first one I purchased is still going strong and the second is now in the back office/bedroom and helps circulate the air from under a desk out into the rest of the room.Still over priced IMO, but VERY reliable. You get what you pay for!

### ⭐⭐⭐⭐⭐ You get what you pay for
*by R***T on June 10, 2025*

I'm on the fence over the price seemed a little high but it is a quality product that should last. I was torn between paying the price or trying a cheaper option. I would go with this one. You get what you pay for. You will want to tape it to the floor to keep it from moving if it gets kicked.
