Sometimes it's pretty comical (for those watching) to witness garden hose battles -- the hose getting caught on the corner of the house, the kinks, the sudden spray of water in the face.
The latest weapon in the war of the hoses is a line of no-crank hose reels that allow the user to effortlessly wind and unwind the hose from a variety of reels and boxes. And why is the reel easy to use? The no-crank system works with a water-powered piston engine that automatically rewinds the hose with the flip of a switch.
