## Customer Reviews

### ⭐⭐⭐⭐⭐ Great replacement part
*by M***N on June 14, 2025*

Works perfect as a replacement for my portable AC unit. Hooks up easily and more securely than the one that initially came with my AC unit. Material is sturdy and there is no perceptable leak of air outside the exhaust. Also is way cheaper than replacement parts from the manufacturer.

### ⭐ Not my favorite
*by D***Y on August 6, 2025*

It did not fit!

### ⭐⭐⭐ That it doesn't come in the size you want.
*by J***N on July 18, 2025*

It doesn't come in the exact measurement that you want.
