Especially handy if you have a distance greater than "classic" between your water supply and machine. Almost impossible to find a pipe of such length in the main large retail chains and DIY which are standard lengths 2m or 2m50. The pipe to the air quality. I had a little trouble to fix the bent side to the machine (I felt he was staring diagonally) but in the end no problem, the binding is strong and not leak. So I recommend.
