Product review (5 stars): Comprehensive kit for installing your water and power line
This kit is nice because it comes with both the power cable, and the water line.  You don't normally need a power line, but things happen and they get lost or broken, so I was thankful to find one.  The hose is good quality, and the fittings turned easily and didn't crimp or twist the hose while I installed it.  It comes with adapters to help it fit on to your dishwasher, which is awesome, because my dishwasher used the adapter, and I was thankful that I didn't have to run out to the hardware store to search for one.
