Product review (5 stars): They do what they are supposed to do (I hope for the price anyway lol)
Well I haven't died yet from the water going through these and they fit perfectly as they should so I give it a 5.  Sure wish they were a little cheaper though.  I don't change when the light on Samsung refrigerator telling me it is time as I am single and while I use water through the filter I don't use the same as a family and these change notices come on by time passed not actual usage so mine last quite awhile.
