Product review (5 stars): Much cheaper alternative
I purchased this filter for my Samsung 4287 HARS fridge.  I had no idea the OEM filters would be like $35!
I settled on this filter since it had good reviews and was very inexpensive.  Plus it had Amazon Prime shipping.  Since it wasn't any cheaper to buy three vs one, I just bought one and figured if I didn't like it, I was only out $20.
I do agree with other reviewers that the shape/size could be improved so it fits better in the fridge.  (it seems like it's floating a little rather than fitting snugly)  Even a thick band that wraps around it would make it fit in the tube better.
Anyway, the water from it tastes good, the same as the OEM.  Time will tell how good it's tasting when the "change filter" lights start changing colors.  The original filter water didn't taste great as soon as the light turned purple (like a "change soon" indicator).
I would definitely buy again.
