It works. I laugh at the neg reviews. With ALL frig water filters... You have to line them up first before you push and turn... Otherwize the o-rings do not make a good deal. Doaent matter if one filter has 2 rings or 1... They mount the same. I test the water every change and this one is within .0013 ppm of the brand name filter... And I ran that old filter through 2 reset cycles... No issues. I like this so far. And yes it came with stickers for those whose don't know how to use a sharpie to write the date on the tab... Thanks
