GardenJoy Lightweight 3/4 in. x 100 ft. Expandable Water Garden Hose

: I think it's just the nature of this hose. After all, it's retractable, so it's easy to twist during the process of pulling and retracting. It's very lightweight, so the material isn't that sturdy either. But even the hard hoses sold at Costco can break. 我觉得就是这个水管的特性，毕竟是可伸缩的，在一拉一缩的过程中很容易扭到。很轻便所以材质也没那么结实吧。不过Costco开的那种硬馆子也会坏。
