Product review (1 stars): Samsung DA29-00020B re-designed water filter no longer works!
First let me say this review is for the actual product and not Amazon. Their customer service, as usual, has been excellent.

We have a 2010 Samsung refrigerator (model: RS263TDPN/XAA) and according to the manual and all on-line resources the replacement water filter is the DA29-00020B (aka the HAF-CIN/EXP).  For all these years we've owned this fridge we've bought our filter from Amazon and have never had an issue with the product.  So what does Samsung do, they go and change the design of the cartridge (ever so slightly) and now it doesn't work.

The slightly redesigned filter no-longer works on my particular model fridge.  Let me just clarify one point, the filter does fit into the slot properly however the water DOES NOT FLOW.  I tried a dozen times installing it with and without the water turned off.  Every time the filter would screw in but no water.  Thinking perhaps it was a bad batch from Amazon, I even went to Home Depot and Best Buy and bought one from each of them but the issue was the same.

I've spent several hours on the phone with both Samsung support and with J & J International (the company Samsung uses for ALL their parts).  Samsung support says it's not their problem because there is nothing wrong with the fridge itself. Since the issue is with the filter it's J & J's problem.  Well, J & J says they build the cartridges to match the specs given to them by Samsung so it is in fact their problem.  They also denied any changes to the design of the cartridge!  This back-and-forth was so ridiculous it was like something from an SNL skit!

For those thinking "what design changes", or "is he nuts, they look the same" I'm attaching some photos showing the filter i purchased last year and the one from two weeks ago.

So basically I'm not sure what to do!  I am still using the filter from last year (which is working like a champ still).  Was thinking about trying a third-party filter but not sure if that's wise.
