## Customer Reviews

### ⭐⭐⭐⭐⭐ as expected
*by K***Y on July 14, 2024*

exact same fit as my original model that started making noise after about 15 years

### ⭐⭐⭐⭐⭐ It works!
*by V***T on October 24, 2023*

It was fairly easy to install. I would definitely install the condensation bypass like in the instructions. It has good CFM and has dropped the radon from 10.5 down to .48.

### ⭐ the product only last 1 year 1 month
*by K***G on February 25, 2025*

This product is of poor quality. I purchased one, and it only lasted for a year and one month. It also caused my ceiling to leak. The worst part is that it claimed to have a 5-year warranty, but the vendor used various excuses to avoid honoring the warranty service."
