The length of the hose is measured exactly 12 cm as on my picture though is recognizable, but not 100% to see because of the angle. The 4-5 mm black thread of the tube is rotated in the tap, so that the hose length is visible after installation 11.5 cm.
My entire knowledge I would like to present an overview.
BENEFITS
+ Flexible extension that allows washing of large dishes or cleaning up the sink slightly
+ Pleasant water pressure so that it no longer injected in the basin
+ Saves money and the environment
+ Water is provided with air so that the user is indeed like the same amount of water exists, but significantly less leaking from the aerator
+ The water feels "soft" on
+ High-quality product, not plastic or Billigkram
+ The aerator with hose extension paid for itself quickly
DISADVANTAGES
- Is certainly not on every faucet, for example in the bathroom, because the hose can be disturbing or
- Make sure that the water tap is pretty high, because the hose "steals" 11.5 cm depth of the basin, so that there will be trouble if you want to wash a large pan, for example.
Overall, we are very pleased with the aerator hose extension. Our water saving is in the kitchen about 50% to the previous water consumption with conventional aerator. I therefore recommend the product in any case continue and forgive because of the meaningful combination of potential savings and flexibility like 5 star.
