Product review (1 stars): Off-taste and hard to install
I had an extremely difficult time installing this filter in my GE refrigerator. Looking carefully at the threads on this and a genuine MSWF filter, I could see that the shape wasn't quite the same. It's molded plastic; how hard should it be to get that right? I fought with it for a good 5 minutes before I was able to wriggle it into place.

I followed the instructions for preparing it for use, then running gallons of water through to get it started. I've been using it for at least a month, and there is a consistent off-smell/taste to the water that we've never had before (and that isn't present out the tap). I'm back to Amazon to buy a real GE MSWF filter, and will toss this imposter out.
