Product review (3 stars): Great but there's a flutter sound on the highest speed
We have recently renovated our kitchen to which this hood fan is going. We are finding that when the fan us on the two lower speeds, it sounds fine, but when on the highest speed, the fan has a loud and annoying fluttering sound that we have no idea about. We initially thought it was the vent, but it's not. If anyone know how this can be fixed, please reply to this review. Otherwise, on an aesthetic basis, it's beautiful and compliments the kitchen and other stainless appliances nicely. Just working on the functional part.
