Product review (5 stars): making it useless. Of course
There are a number of generic filter refills out there and they may be the same size as this one, but the problem comes trying to hook them up. The cheap one I bought at Walmart had a different female connector than the GE, making it useless. Of course, you cannot tell what type the opening is until you peel off the plastic, which you cannot do before buying it. I recommend saving yourself the hassle, spending a little more and knowing you will not have any problems for 6 months.
