Product review (5 stars): Wish I bought this two years ago.
It's cheap. It's simple. And it works! It doesn't fix the flawed design of the water line freezing, but it sure it makes it easier to de-ice compared to hairdryers or keeping the freezer door open for long periods - and I don't have to worry about items in my freezer melting anymore.

I'm sure I could have made this myself for cheaper, but at $10 is it worth my time? No, so I highly recommend this product.

Another side benefit is now I know WHERE the line is freezing, so if I want to insulate the line at the problem area I have a better idea what to do. However, it's so easy to de-ice the line now I'm not sure I will.
