Everything Included and Easy Assembly: The all-in-one unit comes with a pre-installed ultra-flexible hose and a wall-mounted design, avoiding possible accessory accidents and physical installation efforts. Stop At Any Length: Toggle lock mode with light pulls to lock at any length as desired, with no kinks and tangles. Automatically Arrange The Hose: G-Self-Layering System makes the hose fit neatly on the reel. The hose feeder is a ball-bearing style that is different from the traditional roller, allowing you to come from so many different directions without damaging the hose. Enjoy A Longer Retraction life: DS Trigger Mechanism (Patent) improves the retraction force of the hose's final few meters, making it simple and hassle-free to store after use.
