Product review (5 stars): No difference between the LG and this one as far as I can tell
Seems to be working flawlessly...  fits perfectly and has no apparent differences from the LG branded filter that it replaced.  I had to run about 8 16 oz glasses of water through it... the water was very black for several cups.  I presume this is normal and after clearing out the black water, the water looks and tastes perfect.  I've had it installed for about a week now with no hiccups.
