Product review (3 stars): Buy-it-now-store cancelled my order  **UPDATED**
I have no idea if this filter is good or not. This was my first try of a non-Samsung filter. I was concerned about this filter not being NSF certified and whether it would work okay in my fridge. But apparently Buy-it-now-store either reconsidered the price they set or couldn't keep their inventory straight and so cancelled my order. I would (will) beware of this seller. I still plan to buy from another seller and perhaps update this review if my view changes.

Update 06/26/13:
I bought this filter from another seller and have been using it for a few months. It is smaller diameter than a genuine Samsung filter. I imagine that combined with increased water pressure in some households is why some folks are having the rattling noise problems. I have not experienced that issue. If you do I would think that you could put a little cardboard shim to fill the gap the smaller filter leaves and that should fix it. This filter works fine in my fridge. I can't tell you how well it filters except that it doesn't really taste any different than the Samsung. I can also say that it still isn't NSF certified (so it probably doesn't filter as well) which is why I only raised the rating to 3 stars. Hope that helps.
