Rated 5 out of 5 by This product worked as discribed and was exactly as we needed April 20, 2015
Rated 1 out of 5 by Good Product when it works correctly however when you have to disassemble after its installed to rewire the factory wired motor so it goes the correct direction as the manufacturer indicates then all it does is cost you money especially when the job is quoted. August 22, 2014
