Product review (1 stars): Maybe it fits, maybe it doesn't.
Didn't fit my LG LSC26905TT even though they said it was compatible.  Seemed like the o-rings were too "plump" so I swapped out the ones with the old filter.  Still had to muscle it in a little, but it eventually went in.  After now reading some of the other reviews, I'm nervous to see what the water looks like.

Making sure a filter is compatible is pretty basic--and important--stuff.  I shouldn't have to reverse engineer it to make it work.  I'm not McGyver.
