That is a great deal. I bought this model about a month ago for $25 or so from QVC, which was the best price at the time.
So far I like it. I can't say that I have tested all the functions but the temperature was consistent with the factory Ford temperature on the mirror.
I also like the fact that it shows the sunrise/sunset and moon phase. Plus it fits on the panel between the side door and the rear passenger side window on the 50 floorplan.
