Product review (4 stars): Replacement water filter for Samsung Brand
I thought I would give this a try since I can get 2 of these for the price of 1 Samsung filter. I haven't had any of the issues that some users have stated.

1)Some users stated that it leaked - I made sure to put the O-ring lube on as the directions indicated
2)Some users stated that it wouldn't fit properly - I did have to move my sliding shelf out to put the filter in, unlike the Samsung filter which I could put in without doing that (not a big deal, unless your shelf does not slide)
3)Some users stated that it would not align and screw in correctly - I looked at my original Samsung filter to see how it aligned and I just copied that when putting it in.

It looks to be about the same as far as dimensions, however, this replacement filter is much lighter, which leads me to believe cheaper materials, but I really don't know. There is a funny taste initially, but it's the same with the regular Samsung filter. I made sure to run a few gallons through initially. We are light water drinkers, but it's been about a month and the taste is clearing up.

Overall for the value, I think this is a great replacement for those who want to save money. I gave it 4 starts because it is not an exact replica for Samsung's quality and ease of replacement. But if you follow the 3 steps above, you will have no problems with it from the start. I plan on continuing to buy this product for water filter replacement
