### ⭐⭐⭐⭐⭐ Works great
*by J***L on April 29, 2026*

Great product

### ⭐⭐⭐⭐⭐ Expensive trash
*by L***E on June 11, 2026*

After two nights in use, fan blades caught the shroud and bent it. Noisy, one speed. We had to trash it. Blades bent🤬🤬❤️🫶

### ⭐⭐⭐ Great fan, noisy louvers and no insulation
*by E***K on July 23, 2026*

Great fan, but the louvers make an unholy racket while it’s running and it leaks hot air in the winter. We made an insulating block that we stuff in above the louvers during winter to seal off the attic, but that really shouldn’t be required. I think this design is good for something like a workshop, but the quietcool design is better if this is going to be in your house.
