Product review (4 stars): Its the right item for the job..
There's not much to review with respect to this filter.  Its the "official" Samsung filter for my refrigerator model, and it arrived, fit, and was easy to install.  I didn't have my water tested before and after, so I can't say how well it works, but it seems to do fine..  I think its a little overpriced, but when you buy a new fridge, you know what you're getting in to, and the fridge itself is great, so needing a new expensive filter occasionally isn't the end of the world.
