The end caps at both ends are plastic and fragile enough. The design in these areas is poorly done: in fact if you squeeze gently, the water leak is ensured and if you press harder this can break the plastic caps what happened to me. Having home solid tips I wanted to replace one that was cracked, but no way because part is attached to the pipe and is not removable. I do not know how long it will take the other end. Even if the pipe looks solid, I'm afraid we just throw if the other end, not removable I remember, too sensitive. Another point on which I am disappointed: the length is certainly not 23m.
In the end that he remains positive: - Lightness - The flexible portion to me looks solid.
Conclusion: it's completely stupid to have a flexible that is solid if both ends, irremovable, are fragile. If one is forced to throw some breaking everything.
