Product review (5 stars): Save money, work great.
Work great in our Samsung fridge.  There's a tiny bit of water leakage from the dispenser when freshly installed, I would suppose because the filter inside the unit is expanding to max size.  The instructions say to dispense 4 litres of water after installing, and I only dispense about half that, so that could be the reason for the tiny leak for the first week or so.  It's not enough water to overflow onto the floor, and is short lived, so for the excellent savings, these are well worth your money.  The first one I installed was right after my Samsung brand filter expired, and I could not taste ANY difference in the water or ice that is dispensed using these filters.
