Not much to say really other than these were purchased to replace/upgrade the original motors in my 2001 silent master S5.
The original motors were still working, but were getting loud and would occasionally trip with a built-in circuit breaker.
I took this opportunity to upgrade the wiring as well using the appropriate circuit board also from this website.
Everything went together without any difficulty, and I fully expect these motors to be in service equally as long as he originals.
