Works but took some effort
Gets the job done for the price. Quality is average, not quite OE feel, but acceptable for a daily driver. Just verify your fitment first.

Okay for the price
It works, but I'd recommend confirming fitment with the team first. Mine needed a minor adjustment to seat properly. Decent for the price.

OE quality at a fair price
I've bought from the dealer before for twice the price. This was identical quality and saved me a good chunk of money. Shipping was fast.
