Product review (5 stars): Save yourself the time and hassle.
I tried for a long time to get my fridge water connection hooked up before I went ahead and bought this connection instead.  Please, please, save yourself the time and aggravation and just buy this kit as opposed to the tubing and connections separately and trying to make it all fit yourself.  For the extra couple of bucks, you'll save yourself a lot of time and trips to confession for the inevitable string of profanity that's bound to come out of your mouth doing it yourself.
