Product review (4 stars): Great replacement
I always check reviews and this product was well regarded.  Since this was the first filter I had to purchase I was shocked at the roughly $63 cost for the real thing.  I received the filter the next day ( helps to live close to a fulfillment center) and installed it with ease.  I did have to run water through the filter for a couple of days before it tasted "normal."  This was clearly more than the 3 gallon flush that is recommended.  Not certain why it took so long but all is well and really worth saving a ton of money.
