Product review (5 stars): 1 year later, still satisfied. Bought more of them!
Bought 2 of these. It was still cheaper than one Samsung unit that way, and if one was a dud, I wasn't left without a filter change.... Anyway, the first one I tried DID work, no leaks, and the water definitely tastes different and better now (the old filter really needed a change...). These have the NSF certification, which is important.

UPDATE: it's almost one year later. Just bought my third of these filters. Very satisfied. Had no issues whatsoever! I'm happy that I'm not getting ripped off by Samsung!

If you need a new filter, get this one.
