Prima with little improvement

From the sound of her it is much quieter. Only now and then ists times louder, probably is related to the respective prevailing water pressure. The scheme is also fine, even at low flow rate, rarely pulsates this and can not settle itself.

The operation will be trouble with wet hands.

What I find worthy of improvement:
- The effervescent mode could be a lock-tolerated, so that it remains active even at low flow rate.

Another note about the included S-connectors: I have the impression that there is put rubber pieces are not the seal, but the noise reduction. I have the battery only screwed to the old ports, but then decided to use the supplied connectors. On noise but I did not notice it.
