Product review (4 stars): work well for great price
Definitely a good price for filters.  Not sure how long they will last, but going good for a month now! Water tastes ok. Had to flush it out a bit at first, but it fit in well.

Just fyi, after installing it, you need to run it a bit.  This is normal because it has to get all the air out of the line, and then it works quite well.

 I received this at a reduced cost in exchange for my honest and unbiased opinion.
