Product review (4 stars): Almost a Perfect Replacement
My icemaker in my SAMSUNG RSG257AARS refrigerator kept freezing up where the drip tube drops water into the ice tray. I blew a lot of time fiddling around in there and researching online before concluding that it's probably the water inlet valve. I think that when the icemaker was not signaling the valve to fill the tray, the valve would not default back to a fully closed state; some tiny bit of water was allowed to dribble in slowly, freezing, blocking drip tube, and ultimately leaking down the refrigerator door.

So this inlet valve looks somewhat like mine and the Amazon website said it was compatible with my refrigerator. But two things are much different. First, this replacement valve has nice male push on connector ends. The one in my fridge, however, has the wire going into the valve with no connector, I had to cut. Second, the mounting bracket is entirely different. I thought that it would be easy to swap with my current bracket, but the metal brackets are shaped around the valve and I didn't want to attempt to separate them.

Alright so does it work? Yes this valve works great so far. Without the mounting bracket, the valve is kind of left to "float" there, suspended by the three water tubes. See the attached picture. Water dispensing works now, and I've witnessed a proper ice try fill. It will be a couple days after ice is made to capacity before I can tell if this solved my problem.

While this is a review about this valve, let me say that this Samsung refrigerator has been nothing but problems since we've had it. This icemaker difficulty, water down the door, the ice door spring broke and fell into our cup as we were dispensing ice. I'll buy Samsung monitors and TV's, but this is the last appliance.
