In fact, the water is very unkontrollert run from the part out. It has a greater length than the low parts with discharge from art glass, where the light is coming better advantage.
The part is now on the shelf, because I do not even want to use it in the guest sink.
Conclusion: Who has no claims to the water jet and the considerable length does not interfere, gets a little LED light to do so. Otherwise it engages better with the cheaper LED shower spray or waits until something worthwhile comes on the market.
