Product review (4 stars): Seems to fit my Samsung refrigerator just fine as the WSS-1/DA29-00003B replacement
Seems to fit my Samsung refrigerator just fine as the WSS-1/DA29-00003B replacement.  No leaks as some have reported and the five gallons of water moved through it when initially installed seems to work.  Using a TDS tester pen of my ZeroWater pitcher I got these  results:

Gallon  TDS Reading
  1  148
  2  38
  3  36
  4  35
  5  34

Tap Water from the faucet was 37 at the time of these readings.
