Product review (5 stars): I've been using this filter for 3 years now and it works just fine on my KitchenAid KSRL25EXMSO2!
Not sure what all the negative reviews would be for unless these customers are buying the wrong filter for their fridge.  I have the KitchenAid KSRL25EXMSO2 which is only 3 years old (bought from Lowes) and although listed on Google at an accurate Model number it's not listed here on Amazon.  Nevertheless, this is the one I've been using at the water is noticeably better than my tap water but I'd say we must be going through more water than most because it says to change every 6 months or 200 gallons and we tend to get the red light every 2 months.  As an engineer I can tell you that there's nothing wrong with resetting your redlight and running it on the same filter twice if you are the same because the truth is the dirtier and more clogged the filter gets, the more pure the water will be as it is filling in all the larger poors making it harder to flush through much like how you have to put diatomaceous earth in your pool filter to make the pores even smaller for dirt to filter through.  Great filter, have no reason to change brands unless I can find one with a three stage filtration like this for less as $50 plus is a bit steep for such a basic water filter (all the more reason to reset your refrigerators warning light on the same filter to double up it's use time).  Hope this helps someone.
