Product review (1 stars): Doesn't fit LG SGF-LA50 replacement filter!
Sorry for the downer, but these filter do NOT fit my LG as a replacement for SGF-LA50 filter.  They look like they should fit, but will not "lock into" the filter receptacle.  I tried two of the three and neither would screw in.  To my shame, I tried forcing it - as I said, they LOOK like they should fit - and broke the female receptacle in my LG.  Upon closer inspection, the "threads" are slightly different than the filter they replaced (a SGF-LA50).  I have requested a refund from Amazon.
