Good part, works well
Fits well and feels durable. Hardware was included. Knocked off one star only because the instructions were a little thin. Shipping was fast.

Works but took some effort
Part works fine but the fitment was a little tight on my vehicle. Double-check your trim before ordering. Once installed it does the job. Just verify your fitment first.
