Product review (4 stars): Insurance for my washing machine hoses.
Installation was okay.  I had to make some on the fly adjustments to get my on/off valves to fit on the stand-pipe side.  I had no trouble getting the connection to fit on the washer side.  I was still able to get full on/off, but had to work around some interference from the valve handles/flags.  This was not anything short for the hoses.  I also had some minor trouble bending and moving these stiff hoses for my particular installation.
I am a bit worried about the five year replacement time, but they appear to be of excellent quality.  I have not tested them to verify if the shutoff works or the alarm.
I think I would purchase these again for the "peace of mind" when on a vacation.  They seem to be better than the standard rubber hose and about the same price as the steel flex hoses.
