Product review (5 stars): Slightly different than factory filter but it works great!
I've had this installed in my samsung refrigerator for a couple of weeks now and so far it is working perfectly.  As many of the other reviews have mentioned this filter does have a square connection on the end instead of the round that came with the factory filter.  This did give me pause but I decided to give it a try anyway.  I plugged it in and it worked without issue and after several weeks there has been no signs of any leaks.

Another reviewer had mentioned that after they plugged it in they got sputtering of the water as if there was air getting into the line.  I did experience this at first as well; however, I also experienced this with the original factory filter that came with the refrigerator.  After I ran a decent amount of water through the system as you should do when you install a new filter the sputtering went away and it has been working perfectly ever since.

I have not noticed any change in the taste of the water from the factory filter and overall am very satisfied with this for the price and as long as I don't experience any other issues I will most likely continue to purchase these filters in the future.

My one comment about this filter is that the shade of white is slightly off from the factory filter (a little more yellow) which makes it stand out just a little bit in the refrigerator.  But that alone isn't enough to make me want to spend the ridiculous amount of money that Samsung wants for their filters.
