I had it installed yesterday. here are three things.

1. The LED light was not that bright.
2. It did not have touch screen panel and clock show in the photo.
3. The product misses a screw on the front right end (I bought used from Amazon Warehouse).
4. After installation, the unit vibrates ( not big vibration but micro vibration. that increase the noise level when operation).

I would return it. but it just too much effort to take it down. Also, Maybe the unit was an old model since it has a physical button instead of touch screen. the unit did not see that strong. 800CFM. I don't know if anyone tests it.
