Product review (2 stars): Cheesy fake
The product is advertised as an exact OEM but it has a flaw in the mount molding.  The LG filter has a pair of hexagonal mount love cos,  this one uses rectangles, a sign of poor design and lousy quality control.  Obviously a cheesy Chinese fake.  I modified it and made it work but most folks will either damage the fitting in the fridge or have to return it.
