Product review (1 stars): Beware; it appears they are selling a cheap knock-off
I have ordered this item before without issue but for some reason this time it came in a plain white box instead of the typical branded packaging.  I suppose I should have been suspicious of this but without giving it much thought I installed it in my refrigerator.  After flushing a few glasses of gray colored water through the line until it came out clear everything seemed fine.  Twenty minutes later I came back to get a glass of water and the water line is now blocked and water will not dispense from my refrigerator.  In the 8 years that I have owned this refrigerator and replaced filters on it this has never once happened so I can only conclude that since this item was not in manufacturer packaging I am guessing that the were supplied by someone other than the manufacturer.  Don't buy this unless you want it to destroy your refrigerator's water dispenser just like it did to mine.  And, no, the issue is not that the water line is frozen since thawing the freezer did not resolve the issue.  I will not be buying this product from Amazon again since, apparently, I can't trust the quality.  Better to spend the extra $15 and buy it from Home Depot.
