The OEM product is just as I expected. Not made of the best materials cone wise, but I knew that before I made the purchase. The speaker will last for the period of time I plan to keep the car. Sound quality is good. As long as you keep the audio a a moderate level.

Item arrived quickly and was the correct part.

Prices were good, but no free shipping takes that away
