Product review (5 stars): Very easy fix. I will say this though
Came home from vacation and turns out the valve got fowled on our older fridge.  Very easy fix.

I will say this though ... the older valve had tubing with a lip at the end.  You will need to cut that off because this device uses a compression fitting and you need to have straight tubing to insert in.  Don't fret too much (I was nervous cutting it).  It will work!
