Bests & Worsts Reviews from Amazon

I'm returning this filter the same day I bought it. The advertised specs on this filter says it is compatible with whirlpool filter model number 4396508. Looks like someone at everyrdrop decided to make an actual design change and this "newer" does NOT fit my fridge. I have no idea why on earth they would advertise this filter to be compatible with something that is not. very disappointed and pissed.
