The smoke made directly a very good impression and is of high quality. The device is well described and equipped with the appropriate mounting hardware. It can therefore be used directly out of the box. The first function test revealed that the smoke alarm is loud enough for my apartment. The sound is still good to hear in the adjoining room. So far I had no false alarms, even though it is installed in a room with fireplace.
In addition to pure functionality that I expect from a brand-name product, I find to be positive to mention: + High quality finish + Well described
The only downside (and reason for the star deduction) - The appearance of the plastic comes in really does not manage to connect with those aroused by the image, expectations.
