Product review (1 stars): The filter does not perform at all like the original
The filter does not perform at all like the original. First, the water flow rate is much greater, suggesting that the filtration is less thorough. Indeed, the flow rate is so great that splashing out of the glass is a real problem. Second, the water comes filled with tiny bubbles to take a minute or two to clear. The original filter put out perfectly clear water.

I have no reason to believe that the unit I got is in any way defective, but I'm going to suck it up and buy an original.
