Since the useful life of the battery is indicated by 10 years, this is regarded as a deficiency or defect. According to imprint on the housing of the smoke alarm, the batteries should last until the end of 2021.
In addition, the smoke detectors were contrary to the description and illustration of gray and not white and were also provided with lettering and model designation on the front panel. The instructions accompanying (User Manual) was only available in English version. There was no information on compliance with German safety standards and norms.
A request to the supplier of smoke detectors: MarketPlace-seller ". SN-Multimedia, Augsburgerstr 670, 70329 Stuttgart" regarding warranty claims did not succeed.
The company SN-Multimedia answered only with an e-mail following content (I quote):
