Installed quickly and easily.  Very flexible without the stiffness of hoses that are only rubber or plastic. These also have red and blue color designators to you or a plumber following up which goes where. This does come in handy!  If you have little space behind the appliance (washer) connection), I would suggest using a 90% connection elbow on the appliance for any type of connector hose. This would help reduce stress and kinks on the hose.
