Product review (3 stars): Strong patience required
I've always stuck with the name brand filters in the past. The Tier1 filter works, but it took a great deal of patience, trial, and error to install it in my GE profile Artica. The GE filters pop right in and twists into place with an easy quarter-turn. These ones take a great deal more effort and I nearly gave up and returned them (I bought a pack of 3). I gave it a few days and tried again. After more twisting and wrestling, it finally locked in and I heard the swoooosh of water. I'm really hoping this first one lasts a good long time because I'm not looking forward to installing the next one. I'll probably go back to the GE filters on my next order for the sake of my own sanity.
