I ordered this to replace a older unit that held up well from NuTone. This unit had two issues when received. First, fan mounting bracket was not straight had to reform hood to get fan blade clearance to prevent it from hitting the filter. Second lamp lens protector came with a broken tab I could not install had to use old one for now I will call to get a replacement (99110437). Little disappointed, I expected a little better quality from a MADE IN USA PRODUCT.
