Product review (3 stars): Not nearly as good as the Samsung one... I tried to save $$, but it's not worth it at all. (Update: possibly worth it to some)
EDIT: I wanted to quickly revisit this review because I've been using this for a few more days while I await the Samsung replacement I ordered from Amazon... After more use, there is less particulate floating around, the hiccups are now limited to just one around 2-3 seconds after I start filling my glass, and the drips are down to just 2-3 right after filling. So, not as bad as it was at first and at least approaching a reasonable compromise on quality if you want to avoid the much higher cost of the Samsung.

But at the end of the day, the water from this still doesn't taste as "crisp" as it does from the Samsung (though it certainly tastes better than it does straight from the tap!) so for my own needs/preference, the Samsung is worth the extra money. But if you can live with these trade-offs, perhaps this filter will be good for you.

ORIGINAL 2-STAR REVIEW:

Would have thought that most filters are mostly the same... But this one is clearly inferior to the Samsung ones that I originally received with my fridge and have used for over 3 years...

1) I flushed the filter as instructed (passed more than 15 liters of water through it) however there is particulate floating in the water...whereas my water straight from my kitchen faucet is crystal clear!
2) The water now "hiccups" every 10 seconds or so as it runs. (i.e. it will stop filling for half a second even though I keep the lever depressed)
3) Bizarrely, the spigot drips significantly (more than 10-15 seconds of drip-drop-drip-drop) whenever I release the lever -- there was never *any* dripping while using the Samsung filters!

It's nice that these seem to have a little more "flow" through them so that my glass fills quicker... But it's definitely not nice at the expense of these other three issues that are much more important! I'll need to go back to Samsung.
