Product review (4 stars): Work well, fit well, and price is GREAT
Seem to work like OEM so far.  Have only used 1 for about 2 weeks and still seems to be running normal.  Stars up for the price compared to Samsung brand.  Star down for the packaging.  When I received these, they were individually wrapped in bubble wrap in a mailing bag.  There was no box or any other packaging; which led me to question the origin.  However, in fairness to the company, the filters (so far) are working as well as OEM.  The water pressure is good and the water taste is good.  I have used other knock-off's and while inexpensive were clearly inferior in terms of water quality and water pressure.  That is NOT the case with these.  They work well and fit well.  I have no problems with the product and love the price by comparison to OEM.
