Can't really say enough positive here about the company. I am a machinist and mechanically inclined.

The filter was leaking and I contacted the company regarding this issue. They went as far as re tooling the mold to better angage both "O" rings for a better seal and sent me a sample of the re tooled filter!

 Not too positive regarding the filtration quality. Not too sure about the genuine $50 maytag filter though either.

For the price it cant be beat though
