Product review (4 stars): Good hoses that may prevent a flood
I had a washing machine hose burst once while no one was home.  Fortunately, the machine is on the first floor of the house which does not have a basement and there was no damage.  It could have been a disaster and these hoses are meant to prevent a flood.

The biggest problem I had with these is the larger than normal ends of the hose that attaches to the water supply.  I have a valve with a lever that goes up for off and down for on.  The ends of this hose prevented the lever from fully going down to the on position and I had to struggle with it to get the end of the hose in just the right position.  Just be aware that these may not work with your valve.  Other than that, I had no problem with installation.  However, these are more expensive than the normal rubber washing machine hoses and according to the directions they have to be replaced every five years.  The regular washing machine hoses should also be replaced every five years.  So why not just save some money and buy regular hoses?  The only reason I can see is that these have an automatic shutoff built into the hose that will turn off the water supply if they burst.  This alone can save a lot of damage, money and headache if a hose should burst.  It is still recommended to turn off the water supply valves when the washing machine is not in use to relieve the pressure on the hoses.
