Product review (1 stars): AVOID - GO TO A REAL STORE TO BUY THIS ITEM!
BEWARE - there is something wrong with this filter.  Our water flow slowed down tremendously.  This is labeled as an authentic Samsung filter so I didn't think it was the issue.  We had been dealing with it for months, then finally couldn't take it anymore and tried to figure out was was wrong.  Sure enough, it was the filter.  Too late to return it, but I will never purchase my refrigerator filter from Amazon again.  I knew something was fishy when my filter didn't come with a date sticker, but didn't think much of it at the time.  This was about $20 cheaper through Amazon, but I guess now I know why.  AVOID THIS PRODUCT.  I went to a local Lowe's and bought one for $50.  When I put it it in the water flow was immediately better.
