Product review (3 stars): They got ya by the filters!
You really need to be careful here. GE direct claims that they are the only ones that sell the real GE replacement product. While others say GE, they are not GE, they are GE replacement filters. The catch here is, that GE says if you don't use the real GE filters it voids your warranty and GE is not responsible for fixing the appliance. This of cause may not matter to you if your fridge is out of warranty. I don't really know if there is a  difference in the actual filtering process, or lighting the red light once the filter is full. I've used both, but considering the cost of the fridge, and the difference in prices of the filters, I decided to go back to the GE branded filter. I could be wasting money, but if it needs to be fix, I don't want to hear, "tsk, tsk, you should have used the manufacturers filter, now tis is going to cost you."
