Product review (4 stars): CAUTION - May not fit your LG fridge though it is LT500P 5231JA2002A
I just gave 4 stars just to satisfy the review requirements. Ignore that. I returned the product for a full refund. Here's the reason -

there is nothing wrong with the product per se. BUT, I couldn't hook it up to my LG refrigerator. The requirement is LT500P 5231JA2002A. This filter is that per the description.

However, the subtle difference is in the nozzle -  the two rectangular studs that attach to the fridge are not aligned with the two water passage holes on the neck (between the two black rings). My fridge expects them to be aligned. I checked the current working LG filter and there they are aligned. In this product, even though it says LT500P 5231JA2002A, it is not aligned. Hence when I hooked it in and tried, it started leaking water inside the fridge as the water holes were not aligned.

I am not sure how the other reviewers got it working in their LG fridge. I don't think the product is bad. The price in fact is really good. But then I couldn't use it for the reason mentioned above. I returned it and got full refund.

I instead bought the Insignia filter from Best Buy and it's costlier than this but fits my fridge. Search best buy side for lt500p filter.

Before you order the filter, compare the nozzle structure of your current filter with this filter. zoom into the neck of the filter - check the alignment of the water passage holes with the attach studs - in both. If they match, buy this one.
