Product review (5 stars): The best money can buy
The best money can buy.  Build quality is very good. It does not feel cheap as the one sold in Costco and Home Depot. It looks very graceful in the kitchen. I tried an exhaust fan from Viking of 900cfm and noticed that this much better in built quality and more effective in what it is supposed to do. I wish, the fan noise is little lower, but then this one is much quieter than the Viking fan of the same CFM.
It's 18 months now and I never had any issue and this one this goes a long way.
