Product review (4 stars): Disappointed in performance so far
First time buying this brand, and probably the last.  I'm going to give it a few more days, but there is a plastic taste in the water even after several days of use and plenty of flushing.  I've purchased OEM and aftermarket filters for refrigerators for the last 20 years and this is the first filter to do anything like this.  Was also surprised how much carbon filter particles came out in the water during the flushing process after install.  Took nearly 2 gallons of water to clear.  Haven't seen that in a filter before either.  Can't return it since it was purchased many months ago and held in storage.  Very disappointed so far.  One positive is that it did fit well.
Update:  Out of the blue today, a new filter arrived at the door.  Can only guess it was sent as a replacement based on my comments above.  Installed the replacement filter and it seems to be working better than the original.  I have to say that the customer service was excellent if it was Blue Signature who authorized the replacement. Will revise my rating to 4 stars based on the replacement filter received.
