Product review (5 stars): As good or better than the brand name
Because the brand name (Maytag/Kitchen Aid) is absolutely scalping consumers, I ordered these Waterdrop filters with some reservation.  I needed to wait awhile before posting a review because I wanted it to be a fair assessment of performance.  Now, after several months, I can say these Waterdrop filters are fabulous.  There was zero problem installing it (perfect fit), there is zero difference in water output and taste, and, to top it off, my frig had to be serviced because of an icemaker issue and even the supervisory service tech who came out stated there was no reason to not use a competitor's brand.  He was stunned at the great pricing by Waterdrop and said he'd be having his wife order some for their frig at home.  I will even go so far as to say this Waterdrop filter works BETTER than the brand; the brand always had a drip or two after using and the Waterdrop doesn't.
