Optimal limescale protection - extended lifespan. Good limescale resistance of the mixing nozzle thanks to honeycomb disc technology. The elastic nubs on the showerhead can be easily cleaned of limescale residues with a finger. Simple switching from aerated flow to shower spray with minimal rotation. Denser spray pattern due to two concentric shower spray diameters. The ball joint allows access to every angle of the sink. The mixing nozzle is replaceable. Not suitable for pressureless devices.
