Works great
This wrench fits a few different size filters, so it has a better chance of fitting correctly.

Sloppy but works
It fits too loosely and tends to want to cam out on the corners.

OEM quality for a good price
Great filter elements; been using them for decades. They appear to be exactly the same as OEM, but in more recent years they are about half the price of what the dealership charges. There was much less difference in price between online and dealer prices in the past but the dealer price has just about doubled.
