Product review (4 stars): Worth the price
Although I had to go to Home Depot and buy another set of compression fittings, it was probably my own fault, not a defective product.

Instructions weren't really clear, but common sense and a second try, I prevailed. With compression fittings, if you screw up, you don't get a second try. But they're cheap enough. You get plenty of tubing, and an adequate saddle valve. So if you have a convenient source pipe, hookup can be done in less than half an hour. If you're good, less time than it takes to fill a few ice cube trays.

And this kit is a lot less than you'd pay in a hardware store.

Very pleased with this purchase. Clearer instructions would have merited a fifth star.
