Product review (1 stars): Not the 600A model anymore! Does not fit GE fridges with MWF filter.
Inaccurate listing. This will not fit GE refrigerators with an MWF filter. This product is NOT the RFC0600A model. It used to be but they are shipping a model 2500A instead. I know because I ordered the product two years ago and received the right product. I re-ordered recently from the same listing and received the 2500A. Despite the manufacturer's claim to me that it is an updated replacement model, it is clearly not the same connection type.

Compared to the 600A, the female connection is clearly different. In the 2500A, you can see two black gaskets and an inner plastic ring high up in the shaft. That inner ring was not present in the 600A and prevents the filter from seating high enough on the male fridge connector to be able to securely twist and lock.

In sum, if you need a replacement filter for the MWF, look elsewhere.
