Product review (5 stars): Perfectly fine replacement for my samsung fridge
Make sure to turn off the water first (the water pressure may prevent the filter from locking into place); twist out the old one and then twist this one in.
The filter comes with a set of stickers to mark the date when changed- the original filter was in the fridge for 10 months and it did appear to have some mold around the nozzle. I will probably replace my filter every 6 months.

Much better price on amazon versus best buy / etc.
