Product review (3 stars): Works well but not for long.
It installed and functioned just fine. In my opinion the problems many folks are have with it is the proper amount of force needed to seat the filter just right. It's a tight fit, but this fact would be the same on any would be the same no matter what brand of filter you would buy.
For me, the problem with the filter is that it didn't last long at all. The original LG filter lasted for well over a year before the indicator flashed to remind me to replace it. This replacement lasted three (3) months. I guess dollar for dollar it works out about even with OEM filter, but the hassle of replacing it would be 4 times the rate.
