Product review (2 stars): No consistency
I bought a few of these in the past and they worked well but the most recent two I got caused big leaks. In reading other reviews I think all the people who are calling it a poor fit are actually seeing high back pressure that overcomes the oring seal. If you put your lips over the top hole and blow on a working filter, the water inside will fairly easily come out the side holes. On the bad filters I cannot get any flow no matter how hard I blow. These aren't a heavy duty print seal anyway so when the fridge water can't push through the filter, it will spray all over the inside of your fridge. I'm testing now to see if I can soak the filter and get it to open. I'll update the review if I have any luck.
