Product review (1 stars): Water has a plastic/chemical taste.
This is the second time I purchased this filter.  The previous purchase (late 2015) was great with no problems, tasty water etc.
This time around I wasn't as lucky.  The first clue was the extended time it took to flush the filter.  The first gallon of water flushed through was black. After that it was gray until around gallon 4. Then after wasting another 2 gallons it finally ran clear.

I've read the most current reviews and it seems there are quite a few similar problems.  I won't be purchasing this brand again.
