This is my second hammered copper soffit vent from CopperLab. Excellent quality, fantastic looking. I'm actually using these vents for my kitchen stove exhaust hood. I found one vent limited the flow on my hood so I'm pairing another one next to it in the soffit and installing a wye on the ducting to increase volume. I have not installed the second vent yet... waiting for a little warmer weather. You can see that the copper has darkened on the first one from almost a year of use. It looks great on my stone sided 1915 Craftsman style home. When I do a complete remodel of my main bathroom I will be using a CopperLab hammered copper vent as well.
