Product review (5 stars): No leaks, great water!
I bought this as a replacement for the (overpriced) GE MWF filter. I was apprehensive after reading reviews about leaks, but I've had no problem installing and using it. The filter comes with a small rubber 'O' ring at the top (unlike the GE filter). The ring is likely to fall off when you fill the filter with water prior to inserting it in its slot. I was careful to make sure the 'O' ring was in place and flat, inserted the filter and locked it in place. I emptied the first couple of gallons. It has been working fine, no leaks, no carbon residues, and the water tastes great! I don't think I will be going back to GE filters ever.
