Rated 3.7 out of 5 by 31 reviewers.
Rated 4.0 out of 5.0 by Check before you buy! After reading other reviews here I decided the best thing would be to check the item in the store before purchase. I opened a box, took out the turbine and gave it a spin. Sure enough, it made a clicking sound. I looked for interference between turbine and support and there was plenty of clearance, so it must have been in the bearings. The second one I opened spun silently. My advice, check it out before you purchase, save yourself a trip back to exchange. December 8, 2011
Rated 4.0 out of 5.0 by Too Easy I needed a replacement for a turbine that had failed on my house in Corpus Christi. Just changing out the fan portion by itself saved me loads of time not having to peel back shingles that were 20 years old. Removed 3 screws, the new holes lined up perfect, VOILA' ....done. The trick will be; #1 Does it survive an environment where the wind blows 20+ mph every day, and #2 Does the finish survive coastal/corrosive air. Time will tell....... December 24, 2014
Rated 5.0 out of 5.0 by Turbine replacement Well made, balanced and appear to be durable. First day up, had 65 mph wind with no problem. These babies are silent! March 18, 2014
Rated 5.0 out of 5.0 by perfect Mine flew off in the last storm. This one fit right in place. Only request is that they shipped it with self tapping screws not standard sheet metal. November 4, 2014
Rated 5.0 out of 5.0 by Turbine replacement I don't know anyone who would want to replace the entire turbine fixture. This kit was easy to install. I would highly recommend it to anyone July 29, 2014
