Product review (1 stars): who is a great handyman and tech savvy
Zero stars-Samsung kept the model number and changed the design. Originally a 2 key lock and filters worked.  Samsung switched the design to a 3 key lock and the water filter does not work even using brute force.  We read that the samsung filters are nonrefundable and we purchased 3 @ ~$100.  However, my husband, who is a great handyman and tech savvy, said that it was not worth taking a chance on getting a leaky or damaged fridge.  Now we ordered  WSS-1 filters (a generic brand) that we used in the pass, and the filter works like a charm at 60% of the cost.
