5Good product, good company.
By Robert L. Smith
I had two of the externally braced version of these installed on my roof in the early '80s. The shiny bare aluminum weathered to a nice dull light gray over the years and they spun quietly through about 30 years of Gulf Coast storms and hurricanes until the bearings failed recently. I called Lomanco with the code numbers on them and they had replacements delivered to my door free of charge. I was slightly disappointed that the new ones are smaller than the old ones. They are about the same diameter, but noticeably shorter, so I think they will be slightly more restrictive to airflow. Still, I am happy overall with my Lomanco Whirlybirds.

2Lomanco Whirlybird Turbine Ventilator
By JayRay
Lomanco BIB-12 MILL Whirlybird Turbine Ventilator I was hoping this would be as good as they claim but it's not. They were easy to install but once they were in I realized that they were not nearly as smooth turning as my neighbors. I don't know what brand my neighbor has but they turn in even the lightest wind and mine just sit there. They spin when I push them and they don't seem to be binding at all but my neighbor said they were there when they moved in 8 years ago and they turn better than my brand new Lomanco.Like good bike wheels, its about the quality of the materials and how they're assembled.I'm going to find out what type they are and buy that brand.

5Wrong item
By Lizzy
This is an excellent item and I have had them before so the actual product I give 5 stars too. However, I ordered this item specifically as it was a brown one to coordinate with my roof. I received a nasty looking galvanised one! Amazon did refund the money but not the shipping costs so all in all dissapointed. They should show images of what they are actually selling, not different items!
