Product review (5 stars): Excellent high quality product...
Excellent product.  I wish I had seen this before I ordered a whole bunch of unnecessary parts. The built in water hammer prevention device is great.

I used a 3/4" Sharkbite Tee to 1/2" connector to break into our 3/4" CPVC waterline.  That was followed with a 12 ft. length of 1/2" PEX piping to get to the box and the plumbing was done.  PEX is great and Sharkbite connectors are the 'bomb'.  I spent extra time cutting into the sheetrock behind the fridge for a clean/tight fit for the box.  I cut two little 'ears' into the sheetrock for the attachment of the box's ears to the existing 2x4 stud.  The cover panel covers the sheetrock holes for the ears so there was no additional patching of the sheetrock.

Having a proper tee in the input line instead of the failure prone 'saddle' valves is another double plus.  My refrigerator did not have an internal filter so had to mount an external filter on the back.  Used 'flexible' stainless steel 1/4" hose from the box to the filter on the back of the fridge so I could move the fridge out from the wall without worrying about breaking 1/4" copper tubing.  The combo works great and looks professional.  I expect years of service with only the water filter to replace.

The wife and I were living in the stone age without an automatic ice maker.  I don't know why we didn't do this 15 years ago when we moved in.
