Title: Easy installation, and noticeable improvement.
Review: I spent a long time contemplating whether to buy this upgrade, with only an incremental improvement over the old fan(688 model), or spend the big bucks on an ultra quiet model, and probably spend a good amount of time up in the attic.I finally took the easy/cheap way out, and I am not disappointed.The old fan was noisy enough when you first turned it on, but it went to a second level of noise after about 5 minutes. Perhaps the bearings were worn, and started making noise after they warmed up. Whatever the reason, it was annoying.The new fan is noticeably quieter(less noisy), and stays quiet. But it is certainly far from noiseless.Marked improvement, easy installation makes this worth the money.Only wish Broan would offer a 1 Sone version. Don't we have the technology?
