One thing about the hose. They usually are stored on a reel. This puts an almost permanent curve into the hose that I have not figured out how to straighten out. Even using HOT tap water, the hose curves back once it cools down.

One more thing, be VERY VERY CAREFUL when you slit the tubing, to NOT cut yourself. I used a utility knife, but any SHARP blade will do. And ALWAYS KEEP YOUR FINGER AWAY FROM THE DIRECTION THE BLADE IS GOING.
