Product review (1 stars): Would no longer recommend
Do not buy. I bought this just one year ago in a two pack and both worked fine so I had no hesitation buying again this year. The only problem is when I opened up my new two pack both filters neither filter worked.  It would appear there is a new design with two black rings as opposed to last years one black ring on the business end. Unless there is something I don't know I feel like this is a scam product offering. Disappointed and returned.

UPDATE: 8/27/18

I returned my filter and was refunded by Amazon. However, after buying and installing the Samsung filter I have figured out that this is not a scam. The issue for this company is that they have updated the product, but have not updated their photographs or installation instructions pamphlet that comes with the filters.

1. The new model does have two rings, not one as pictured on the product's amazon webpage.
2. This is important because installation is now done differently. Instead of being sucked-in instantly with the one ring model, you now have to push with some force as you twist the filter clockwise into place with the two ring model.
3. I suspect this is why you're getting a lot of negative reviews. Either customers think the product no longer fits, or they install it without getting the suction, and it is creating leaks in their fridge :(

In short, I still think this is a product failure. But I'm moving you from 1 to 2 stars.

As someone who makes their living doing graphic design, I would be happy to assist you in creating a new instructions pamphlet to save your company lots of lost money (at least I would imagine you're losing a lot of business).
