Finally a smoke detector, which adapts perfectly to the ceiling and the room. Due to the small size, it is hardly noticeable yet and is not bothersome to the ceiling - in contrast to many old detectors that never were not only much larger but so really do ... The best is however that no battery change is necessary! The detector has a 10-year battery and after 10 years should the detector anyway be replaced. Although the price may scare many, the small size, the design and 10 year lithium battery is already good arguments and, therefore, the smoke detector is also highly recommended!
