Fully functional just not that great cosmetically. I used it for a little over a year but this would rub on the rear bolts that hold the motor for the AWD system. It just drove me crazy and can't take it anymore. Tried to wrap it with some cushion but it still rubbed through and makes ever so slight contact.. Pic shows residual glue in the center with slight marks of the bolt heads. I think the price new after shipping is around 140 or so and I'm selling for $80 shipped (includes pp fees).

After that, it's silent. Unsure if it fits the prime Posted via the PriusChat mobile app.
