Product review (2 stars): Don't have the same design as the original LG refrig. filter
1. I am wondering that the o-ring grease is a good idea and hoping it is food grade?  Sooner or later the grease will come into the water.

2. This filter has no locking position design.  This filter will stay in place, however, there is no locking position as the original filter, so don't bump into this filter.
