Product review (1 stars): DON'T BOTHER
You get what you pay for obviously.  Received filter in an attempt to filter water outside the fridge in addition to the built in replaceable filter.  Had to cut my line to attach and this thing leaked like a sieve.  No way to remove the line once you put it in, so cut it again to remove it.  Problem is in the design with its built in attachment.  I had misread and thought it at least had a screw on attachment.  Not.  You push your line in and that is supposed to seal it.  Well it doesn't.  Ridiculous design flaw.
