Product review (3 stars): Sentinel Wss-2
Filter arrived as promised. Warehouse deals are a good buy with usually just the packaging damaged. Although not an original Samsung water filter, it works as well as original equipment.  So far so good.

Had purchased 2 of these.  The first one worked fine and lasted about as long as oem, but the second one was a dud.  I could not get it to work and it was too late to return.  Don't know how often this happens with filters, but it was a first for me.  I did switch back to Samsung brand, but would consider this one again.
