Product review (4 stars): Works for connecting the ice maker
The valve seems cheaply made but does work.  The tubing and 25 feet is just right.  I used the brass insert and brass nut included on the valve side and it did not leak or come apart.  On the refrigerator side I used plastic nut and plastic compression washer because that was what I had used previously.  I believe I could have used the brass insert and brass nut because the connector on the refrigerator had a brass insert but I did not try.  The price was right for the kit and was lower than the local home store that had the exact same kit.
