Product review (5 stars): Filter went in easy, no leaks, works great.
The filter I received fits perfectly. It went in easy and I have no leaks. Water pressure and flow are good. The O-ring thickness and position on the end of the filter are exactly the same as filters I have previously bought from Lowes. I also compared the box the filter came in with a filter box bought locally. Exactly the same on all 6 sides. Both boxes state the filter came from Mexico. I have never been able to find a filter made in South Korea. I have a shutoff water valve leading to my refrigerator so I always turn off the water and release the pressure prior to changing filters as described in the filter replacement instructions. Never had a problem.
