this is a good pipe. A pipe not too expensive. A very light pipe. This hose is light because it is late. This hose is not twisted. The 12.5mm diameter required, somehow use Hozelhock fittings. Gardena because only the minimum 13mm. Short Tip for otherwise gardena actually 13 mm but with reel. There without reel is good. The Hozelhock pipe is really good. I'm happy with that pipe.
