Product review (1 stars): Put the $7 towards one that works
I am disappointed with this product and should have taken the advice of other reviewers into account.  First problem: the handle on the saddle valve broke when trying to tap into the copper pipe.  I ended up having to drill a tiny hole into it and then use pliers to tighten the saddle valve.  Second problem: the compression fittings are not tight and I have a very tiny, slow leak; I even tried adding some pipe clamps to really seal it, but the hose's outside diameter is too small to make even a 1/4" hose clamp work.

The pros of this product would be that the line was certainly long enough, but that is, of course, relative to where you're tapping into the water line to the location of your refrigerator, and the fittings were the right size to be hooked-up to the fridge.

The cons are that this is cheaply made and the fittings are junk so water is leaking.  Since I don't have time to replace it yet, I had to setup a 1-quart plastic container where the connection is that catches the leaking water.  The leak is slow to where I am emptying the water every 3 days, which is only about a 1/2-quart, but it's annoying.  At least I have a working ice maker in the middle of Summer.

I am going to cut my loss at $7 and go out to Lowe's where there is a highly-rated, simple-to-install line (my brother just did it and said it took him 20 minutes).  This new line will require me to cut-out the piece of copper pipe where the saddle-valve of this line is.
