Product review (4 stars): Saves you money and works great, but it is made in China...
UPDATE: I just received this in the mail today from Sears where we purchased our Refrigerator. $49.99 with FREE shipping for our filter IF we sign up for auto delivery. Sure makes this look pretty awesome at ~$13.50.

To be honest, there isn't too much to put here. It fits perfectly in place of the OEM filter. There was a time, not so long ago, when these filters cost a fortune, upwards of $50-75, which seemed exorbitant compared to the fact that many of the appliances they were replacing only cost $500-$750 and you had to replace them every 6 months. In 5 years you could have purchased another fridge. Kind of like printer ink...

Now, they are much more reasonable, but still the OEM Samsung filters are about $35 each in a pack of two ($70 for the pack) so this is still a nice savings.

I will say that I share other reviewers concerns about the safety of products made in China. I'm not really sure as a consumer how I can check the safety of a device like this - in the end, it will have to be up to you whether it is worth it to save $20 vs the very unlikely (in my opinion) possibility that these might be harmful. Or the more possible chance that they might do little or nothing at all. LOL.

My thinking is;

A.  We have so much coming from China we don't even know half of it - I buy my kids Capri Sun 100% juice and am a kid's drink snob when it comes to giving them Capri Sun drinks (aka, not juice) and I just noticed the other day for the first time, that the concentrate for the juice comes from China. Arghh.

B. In spite of my very real concern about the lack of product safety and government regulation in China, along with a culture that seems to reward performance at any cost, I have to think that this product is less likely to be tainted simply due to the product category and how it is made and what it is supposed to do.  I am hoping/gambling/praying that the worst-case scenario will be that they do nothing to filter.

C.  So far so good... I have not seen or heard of any news stories of this kind of product causing harm to consumers.  I am particularly cautious of things like baby formula, toothpaste and other products that have been spiked with melamine and similar contaminants in the past, as I feel they are more likely to be tainted again due to the way they are manufactured.

So, with all that said, I think these are probably safe even though they are from China and they are much cheaper than the Samsung filters.

Your mileage may vary.  I think that I may cut mine open to use as a demo rather than actually use it on the fridge now that I have made myself second guess it. LOL... Seriously though, my best guess is that these are a great way to save money and filter your water/ice.  After looking at the product some more, I feel comfortable with it. I sniffed, stared and scrutinized it as much as possible and I am going with my initial opinion that this filter is probably just fine.
