Product review (1 stars): STAY AWAY!  Bad metallic taste!
This filter added a terrible metallic taste to my water.  I ran water through it several times a day for over a week to give it a chance to clear up, just in case that was some impurity from manufacturing that would wear off.  However, it has not improved substantially.  This may be the cheapest filter available, but, in this case, you get (less than) what you pay for!
