Product review (4 stars): Simple Installation and Quality Construction
In the course of remodeling my kitchen, I added a water line for my refrigerator ice maker. This was my first plumbing project I've ever done, and I thought it shouldn't be too difficult, but I wanted to be sure that I got the correct materials and supplies so the project was a success. This quarter-turn valve was exactly what I needed.

To install, I cut open the drywall across a single stud bay in my wall, ran PEX up through the wall, and used a valve that had a sharkbite connector on one end and threads on the other end to connect between the PEX and this ice maker outlet box. It was incredibly easy. And now I have a valve right in the wall to connect to my fridge. It's a much more durable solution than a saddle valve and a 1/4" copper or plastic pipe.

Update, 2013-09-09: Removed 1 star. After putting the patch of drywall back in, we realized that the drywall had an obvious bulge where it laid over the tabs and screws where this box attaches to the stud. We had to do several things to alleviate this issue: First, we tightened the screws to make them flush with the tabs, which caused the plastic edges of the tabs to split, but it is still held in place very tightly. Second, we cut out the back of the drywall to make the drywall thinner where it overlaps with the tabs and screws. This worked, but I wanted it to be more like an electrical box, where you just have to cut out the hole and hang the drywall back over the new box.
