Product review (5 stars): Perfect alternative...  ...and MADE IN USA!!
I have been using these filters for almost two years.  I would like to say that they perform flawlessly and fit and function is as good, if not better than they Samsung part that they are made to replace.  The bonus is that they are made in the USA and in my opinion, I'm happy to help support our floundering economy by supporting American companies and buying American made products, especially since this one is about 1/2 - 1/3 of the cost of the original.  I did my research and read many reviews on the product before my original purchase.  I noted that one unsatisfied customer reported that his filter literally burst at the seems and made a huge water mess in his refrigerator.  I can't speak for that customer, but I guess it's possible that ANY filter of ANY brand could do the same.  My guess is, that customer works for the competition and is merely badmouthing, a quality competitor, that builds a great product that functions perfectly and is built right here in the USA.  I'm completely happy with my filters and just ordered a 3-pack, saving even MORE money.  Thanks Water Sentinel.
p.s. Just so you know, I'm just an average consumer that does a lot of maintenance and repairs myself to my own home and the products I own.  I'm not a vendor of anything.  I'm a retired US Sailor.
