Product description itself on the Gardena site

Hose reel is impeccable, inspired me.
Beautifully informed on the original page Gardena,
Max. Capacity 13 mm (1/2 ") 50 m
Max. Capacity 15 mm (5/8 ") 40 m
Max. Capacity 19 mm (3/4 ") 30 m

BUT: 50m 1/2 hose would fit that someone has been able to very accurately roll so that the dream comes true. For better quality hoses that are highly flexible and bendable (even enthusiastic) as the premium of Gardena is at about 40 meters final, for the rest of the meter you have to come up with a different variant. This role is likely to be for the best Gardena hose then it could be the 50m match.
