Main focus was a perfect speaker function, the overall voice quality and the ECO Mode (low radiation !!!) for me. All 3 points have now convinced me after about 3 weeks commissioning and thus the "Dune" has earned the 5 stars.
Of course the phone on top also contemporary Options has as "room monitor" or "scheduler with alarm". Both practical, but who today :) no smartphone or tablet in the house.
Short and sweet: high-quality, graceful design, great voice quality, many additional functions.
