Product review (4 stars): ACCEPTABLE REPLACEMENT, PROMPT DELIVERY
These things are perfectly good replacements for the name-brand, as far as I can tell. They arrived about 6 hours after I ordered them. They are incredibly difficult to insert (for me). Be prepared to mop up water from the outgoing filter and use pliers to remove it. Push the new filter like you're trying to shove it all the way through the fridge, and don't give up once you get started. I realize my comments and the 4-star (instead of 5) rating have little or nothing to do with the quality of these filters, but there ya go.
