Product review (1 stars): Poor quality control and performance.
The item arrived with dings.  They were not discovered until the protective film was removed and after the installation was completed.  Amazon was kind enough to make a concession but the vendor clearly had mishandled the product during their manufacturing process.  The shipping box was in good shape and the damaged piece was stored inside of the outer sleeve during shipping, so no way that the damage could have occurred during shipping.  Secondly, I doubt that the CFM is performing as advertised.  My 100 CFM bathroom pulls more air.  I've checked for blockage and the baffles are opening properly.  Definitely would not recommend this fan.
