Product review (3 stars): Different design at the top of filter causes problems with fitting into fridge
Updating to 3 stars because the customer service deserves at least 4 stars though the product doesn't fit all fridges that use the MWF filters. They refunded me within a day of my issue. Very happy that no money was lost in this transaction and I didn't have to fret :) thanks!

I bought the 2 pack. Opened one immediately and followed instructions. It refused to fit nicely. It either popped back out and spilt water everywhere or when it stayed in, the water did not flow. And yes, I did pre-fill the filter with tap water first.

After multiple attempts I decided not to spoil my fridge and put back the original GE WMF filter which worked just fine again. Going to buy the original brand now. I also read that the filter ratings are different between the replacement brands and the original. So just be aware.
