Product review (5 stars): Excellent bargain compared to the ridiculously overpriced GE-branded filters.
Its been a little over a week and I've had no problems to speak of with this replacement filter.  Its a much better price that the GE branded item.  I'll update when I have a good idea how long it lasts.

*UPDATE* - It's been about seven months since I installed this filter and I've never had a problem with it, but my fridge says it's time to replace it.  I'm buying another without reservation.
