Product review (3 stars): The jury is still out
I may update the rating at a later time, but let me tell you a little about this.
The filter is about a 1/4 inch shorter than the original filter or OEM filter.  When I flushed it before starting to use it, I had to flush a lot more water through it in order for the water to run clear, as compared to OEM filters.
A few days after putting the first filter in service I noticed dark sediment in the bottom of my glass which looked just like the dark charcoal powder you flush out when putting a new filter in service.  It only happened the one time but makes you wonder.
The price is about 1/3 the cost per filter, but if you get sediment what is the point.
Time will tell.
