Product review (2 stars): Extremely hard to remove!
The 1st time I bought this cartridge, I was replacing the one that came with my new refrigerator. I took the cartridge that came with the fridge out with no problem and inserted yours. So when it was time to replace it again, we rebought your cartridge, but when we tried to remove your old one, we nearly had to take the refrigerator apart!! It just wouldn't come out! I thought we were going to have to call a repairman. We were finally able to take the section apart that the cartridge sits into remove it. We went ahead & put your new one in since we already had it apart. I can only hope when it's time to change this one, we don't experience the same problem!!!! The cartridge seemed to do its proper function once it was installed.
