Product review (4 stars): Works as intended, good price.
This was much cheaper on Amazon than at Lowe's.  It was easy to install, just remember to turn off the water first. Check your refrigerator's manual for instructions on resetting the filter alert on your fridge.  If you cannot flush water through the filter (my machine doesn't have a water dispenser) be sure to discard the ice cubes, because there will be charcoal dust from the filter (which is normal).
